I ride the Embarass River ATV park in Tigerton,WI very frequently. The motocross track has some bigger jumps but nothing too radical. Most riders/racers can double all of the jumps after riding there. I have heard that the track will be completely redesigned this year to make it more challenging as well as eliminate a few slight bottlenecks on the current track. The trails system is on the small side but it's probably the closest trail system to you in Neenah. Not sure of the total milage of the trails but you can cover every trail they have in a good day of riding. The camping is also good there with both electric and primitive campsites available. I would check out the link that Retro posted for more info.

 

how much does it cost to get in there? are there any big mudholes or anything? could i take the jumps on a prairie 300 or a bayou 220? are there any races held there? do u win money or trophies? could you enter anytime?

 

I believe all the costs were on the page that retro linked to. I think the prices to ride are as follows... trails $5, track $10, but don't hold me too that. It's on the honor system when you get through the main gates but I know they check occasionally. You must also have a valid registration sticker. As far as riding your undersuspended machine on the track, anything is possible. I have ridden my roomates 2001 Rancher 350ES 4x4 on that track without much of a problem, granted I did not try to clear any doubles or go for big air with it. I am unsure of the race dates as of now. You can e-mail Tigerton Race Info and see if they have set any race dates for 2002 yet. There aren't really a lot of mudholes but they do have one challenge course set-up which I heard as a bottomless mud section on one end. That's not my thing. They run 3 race events a year and the park is usually open from Spring to Fall on weekends. They are open during the week I think but I am unsure of the times. Best bet is to e-mail the above link.
