Huh, never heard of it.
It seems to be open for ATV and Off road motorcycles. If it's still in the 50's this weekend, I'll have to take a drive up there. It's only about 30 miles from Newton.
Tama is alright. There is a lot of trails. But, it's pretty flat. There was alot of sand and mud - which wasn't much fun on my 80/20 street tires!
If you want to take a drive - hit the one in Waterloo. Lots of fun terrain there.
