AP,
I have called most of the local ones on the list. Many of them are closed or do not return phone calls. the few that I did talk to don't carry PS even though they have them on the list. I think I will have to do what Bill suggests and catch a few from my local waters, put them in a tank and treat them, then release them in small groups.
Bill, I think I will not try the RES. BG with an occasional surprise PS sounds like fun.
