There is a really great little orchid show put on by the Heart of Texas OS. There's a car charge but I don't recall an admission charge (I have usually worked it, so I may have just not had to pay admission). The WOC in Miami charged $20 per day, unless you registered for the conference. Do any of the judges' fees get reimbursed by the societies when they come judge shows?
Free or not, folks who really want to come will and the maybes won't. If the orchids in the big box stores attract someone's interest, they'll soon join the dark side.....
and be willing to pay any price just to be near these beguiling plants!
