I've only been to one regional about 4 years ago, we had a blast! (Region 11)
I won a daylily and bought a couple in the auction.
If you went to a regional you could meet all the famous Florida hybridizers!
They are expensive to go to, especially when the auction comes around.
I've never gone to a summer one with garden tours though, I think if I go to that for a week I'll miss my peak bloom!
Where's the closest club around you?
