yeah I had 2 twelve hour days there, 10+ of those hours were solid riding, and it was no where near enough! Sure beats STL mud and mundane xc loops. Although, STL trails are 10x better than chicago so I can't complain.
Yerp. I try and make it out there 2-4 times a year. I used to camp there with my 3 brothers 5-6 times a year every year, we grew up 2 hours north of there. Rad trails! So nice.
