Aanvil,
You make me think that things are just done differently in Los Angeles. (I’m a native Californian, btw!)

Just looked up Nyckelharpa on YouTube. Damn, I’d drop everything and be transfixed too!
I also play fiddle and sing the occasional song.
Well perhaps I misunderstood you (my apologies if I have) but it seems like you are of the opinion the bodhran doesn’t count as a valid instrument.
My remark, to be clear, was directed to the many that pick up that simple piece of skin and wood because its “easy” to play.
Anyone can play it… and its painfully clear few can play play it well. Perhaps that is what you were getting at too.
I don’t think that holds any less true in say… Ruskin than in Covina.

It isn’t how many.
It’s how well.
Is it? The topic question does not mention “well”. It is just an inquiry into one’s interests in other instruments, not how good a multi-instrumentalist someone may be.
Of course you could argue that trying to learn, or messing around on, lots of instruments will distract from learning one instrument well and proper, or that it is a wast of time. And that may well be true. Still nothing wrong in having some fun sometimes.
Trying to keep up with:
Flute (ITM flute, bansuri)
whistles
Guitar (longtime player)
Previous mainstays that fell by the wayside:
piano
bass (used to play in a rock band)
mandolin
Where in VT? I live in the Southern portion..
I guess for this thread I should add, in addition to flute:
guitar (electric, mostly - thirty or so years playing rock, although some acoustic, and bass, too)
mandolin - spending more time on this recently - comes and goes depending on how much free time I have.
My bodran is where it should be… on my wall, above the piano.
I’m in the champlain valley near middlebury - quite a few good flute players up in nothern VT (I wish I could count myself as one of them). Any good sessions down there?
No, it’s pretty lonely here, ITM-wise… You’re about a 2hr drive, and no other flute players I’m aware of. The closest session is mostly French-Canadian/NE fiddlers who are fine, but no Irish lift to their playing…I was spoiled by years in NYC, where I could find a session almost every night, and some of the best players on the planet..
Still, no regrets… it’s awfully pretty here, and I finally got my wife to start learning fiddle, so I’m not just playing alone.
So I’ve traveled northwards a bit and met a few good players here and there, near Montpelier (hey David!), and I’m told there are a few decent sessions eastward, near the NH border.. I’ll check them out in the spring. Let me know if there are some good sessions up your way, and I’ll do the same!
I play the flute at Irish sessions. Rarely the whistle (never sounds in tune, people can hear my mistakes).
I play the whistle when I’m alone or in the woods.
I play the mandolin at American Old-time gigs where I’m getting “paid” (I guess $10 or pot luck is payment).
I play the fiddle when we practice the old-time music. I really want to learn.
Flute is what I play best, whistle almost as good (as long as I’m not at the session.)
Main practice instrument is flute, boehm (17 years) and Irish (fairly new to this, about a year).
also been learning fiddle since Christmas and expect to sound dreadful or another few years yet.
beginner on smallpipes, still in the strangling sheep phase.
whistles for noodling in the sunshine / car / office / bath (!)
sing, at gigs and in band
guitar in band but truly, it’s so shocking i don’t know how i get away with it - just hope they’re listening to the other musicians! 
I also play clarinet and tenor sax but don’t practice these … so quality is receeding daily.
I play enough piano to write a tune … and enough cello to write a bassline.
I use laptop to write and perform (sorry tradsters!)

Clarinet–on occasion really messes up the mouth for flute…
Piano, sort of!
Anything I can put my hands on really!
I play 100% by ear, so sheet music is useless to me. I tried learning, but my brain wasn’t liking what my eyes were reading and I just gave up at some point trying to play what someone had decided the best way of playing was…
Is there any special reason for asking this question? I’ve not read all the replies but have or will any conclusion be reached?
Personally I play whistle and wooden flute, I fiddle a little (a sin I know but my flute is pretty nasty too) and button box very little(and that does call for confession). I’d like to play fiddle more but find free time is sadly too limited.I pretty much decided that whatever tallent I may have it is too thin to ever be able to play three instuments well. I feel the fiddle suits me as a second instrument better than the box. Teaching myself to tune it was useful for tuning on the flute. Especially as I have had no classical training. Although the fiddle is very different to the flute I think there is a closer link between it and the flute. Maybe it’s because it has more flexibility than the box. Playing a tune on the fiddle will give me new ideas for that tune on flute and vices versa.
