Cost is like $5 for a car to get in. It is large with lots of vendors of all sorts and all items. Lots of people take their lawn mowers, 4-wheelers, Mules that sort of thing to drive around.
We go every year. I brought all of my garage sale stuff last year and as I was unloading it people were buying it. I didn't even have to set around and wait. You can see everything from chickens to camels! The fun thing (if you camp there) is waking up to 1000+ chickens, guineas, turkeys, peacocks crowing in the morning!!!WOW it is loud! Wear comfy shoes, there is a lot of walking.
we drive 4 hours to go!! I went for the first time last October and now we plan vacations around the swap.
Last October we saw a 4ft alligator, June it was monkeys. I can't wait til this October to see what shows up next.
