We haven't, but there is a campground here that features LOTS of entertaiment, and we are going to try for it for next summer. We did play one night for free several years ago at a state park campground near here-- it was a gospel sing. I can also tell you that whenever we have camped in our pop-up and taken along instruments, a crowd has gathered to listen, and kids have wanted to try out the instruments. For all of these, I could and should have set out a tip jar. I think we blew an opportunity, though we did have a good time. Now we are working up a set of can't-miss tunes and singalong songs. Parents today remember lots of Clementine-type stuff and the kids nowadays are not getting much of that in school. We did a few tunes like that the other night in a local restaurant just to have a place to jam a bit, and we got two gigs out of it from people who were there. And it was all old stuff the adults knew and the kids liked but had never heard.
