I just googled 4-H rabbit camp (yup that is how bored I am lol!) and there seems to be one in quite a few states. Maybe certain clubs do it and some don't.
I know that there are lots of rabbit clinics in my area. The local rabbit clubs in my couny put one on every year and I'm definitely going this year, as I haven't gone in the past.
I might be going to a clinic this weekend, actually, with my 4-H leader and her sons. Should be fun if we go!
