I'm not in Ocala this year, but WEF instead, but I had the ponies there the last 2 years. The market is generally pretty good. Ponies sell well, if they don't have holes. I wouldn't hesitate sending one there, but send it to someone who has buyers like, Bibby Farmer or Emil Spadone. Don't waste your time sending it to someone who doesn't have much traffic.
Once the shows are over the place clears out completely, so don't waste your time keeping it there after the shows.
