I've been to those growers you saw but I have no idea who they are!
I was on a buying trip with a few members of our local club when i first started with the chids and wasn't paying attention (didn't know any better then
)
I'd say just stop at each one and ask if you can go in. I don't remember being turned away from any but I don't know if that's because I was with the President of the club or not
Let us know what you find out...and get names and contact info!
