Please post details about that show, Jillz!
We get together for a fall plant swap / party and also do an annual seed swap at the beginning of February. The seed swap has been at Chef Lin Chinese Buffet in Frederick for many years, but I'm always hoping for somebody to come up with a new venue!
We get together other times, too. Sometimes that's as simple as one person posting they're heading to a nursery or a public garden, and then others join the fun.
