I normally park at Argo, but I'm approaching from the south. Parking at Truman just means that you have to climb to get into the trails, and you have to roll the gravel to/from. We aren't always really good about weed-eating a couple of the pieces that approach from the Truman side, so I don't know if you have to do any bushwhacking through high grass to get to the main trails or not.
Bike racing is good. The people you meet, the struggles you overcome, the highs and lows, the downhills, the finish lines. Bikes in general just make us better people. -Cameron Chambers
