I cut my teeth riding a 3 wheeler at turkey bay back in the 80's. It has changed ALOT over the years.
I kinda liked it better in the old days but the new turkey bay is pretty cool too as the trails are color coded so you will know what you are getting into before you pile off in there.
The "circle trail" is my name for it anyway, is the trail that basically goes around the entire thing.
It would be awesome on a four wheeler, especially the faster ones but the gravel was kinda squirrley on a dirtbike.
I do like it though and we did have a ball up there.
I hope the piece of trash that stole my dirtbike rides up there and hits a tree head on at 80 though.
