I agree its hard to prearrange a meeting. We're 14 strong with a hammered dulcimer, concertina, autoharps, flutes, whistles, mandos and long and short necked banjos, a superb fiddler, and four cloggers, so we should be easy to spot. I occasionally use a large shaman drum which I play like a bodhran, but use a hard felt typanni drumstick instead of a tipper. It gives a softer but far deeper kettle drum sound, so you should be able to pick us out on sight (or sound).
