Are there any drummers in the audience?

I live in Mid-Coast Maine, where there are certainly clubs and bands to play them. But for those of us (older) folks who want to get away from the bar scene it can be difficult to find a niche to play. Enter the "coffee house" scene, which has really taken off here in Maine. How can you go wrong? Coffee, free music (mostly) and perhaps a pastry or two.

The best part about this scene is that you can get home at an early hour, especially if you have to work the next day. The only thing I find wrong with this scene is the idea that you don't need a drummer. Sure, I understand, "we're not set up for it, man". Meaning, they don't want to deal with any kind of real P.A., a sound man, and getting yelled at by the waitress who can't hear her orders.
I'm still determined to get into the scene as a drummer though. And no, not as the tambourine player!
The Cajon drum is just what is needed. low volume, acoustic, and low profile. The benefit of this drum over other forms of hand percussion is that you can get a real snare/ bass groove going because of the low/high construction and the internal snares.
At this point I haven't seen too many (drummers) use them yet, so I want to break some ground here.
Don't get me wrong. You don't have to be a drummer to play one of these. But it certainly helps if you have rhythm!
