Looks like fun! But you need some tires/rims and snorkels on those bikes!

One of the better sites for aftermarket parts and forums(one of the biggest atv forums) is High Lifter Also there is a big mud bog going down on the weekend of Nov 17th in Doles ga(west of ashburn), the biggest in the SE US that is. you can find more info on highlifter or Home Place is awesome, but don't go in most of the water if you arent snorkeled there. Watch where you ride here in fla in the mud. Especially National forest....they fine like $250 per tire that hit the water/mud!
