In my area, to show at local fall fairs, most charge a membership or exhibitor fee, then you get the pass. They get the money one way or the other. You should find out what classes are offered (size, type, single or triple). With miniature dahlias, timing isn't so important. They give lots of blooms. The most important item for you to know, is how to pick the winning bloom, how to display it, and have it in the right class. Do another post with the classes, and then maybe someone can offer the names of dahlias that would be appropriate for you to grow.

the exhibitor fee is in place of course but it is still less than the admission and it is for the entire event, all 5 days (Rodeo included). As for picking my winner(s) I believe the entrance forms come out in June or so. I'll be back...(sez Aaaahhhnald)
