I live in a rural area and have more music gatherings than I truly want. Some of these gatherings are direct descendents of the local musical past but they somehow miss meeting the various definitions of 'folk' I've seen here.
Locally, we just call it Music--as in "are you going to Music tonight?"

I've got a couple boys who are more than 20yrs younger than me and a handful of Olders (by 20+) that I call 'students'. I figure I'm doing my part to make sure we have music in the area for a while. Besides, it's fun.

Last night's gathering was a Gospel Jam in a town with population about 300. There were about 20 musicians and roughly the same number of audience. I don't enjoy gospel much but the townies seem to like it and sometimes while the rest of the bunch is eating, a few of us sit in a corner and play stuff I do like.
The church thing is monthly.

My town has under 500 people and we regularly have anywhere between 5-20 musicians. When we make a sort of formal invitation, we have townies sitting around visiting/listening. The rest of the time, our audience is a handful of wives.
That one is weekly.

So, no Folk Scene around here, but Music is alive and kicking in this particular rural area.
