Graham Swamp was awesome!! Me, Kevin, & Mark Peck went. It was only like a 45 minutes drive and all 3 bikes did great on my bike rack! It was with out a doubt more extreme than hanna Park but at the same time alot slower due to alot of up hills. There was some soft sand but alot less roots. The big down hills were awesome! There were 2 down hills i wouldnt do and alot of ramp/jumps i wouldnt touch. Alot of it is also very technical. I will go back and often it was a nice place not too far away that can be done after work!
