Okay guys, had a nice talk tonight with our ranger at Arkabutla Lake about the pump track. Conveniently the ranger and his wife just moved two house down from me and talked with him after my ride this evening.
They have the "okay" for us to build the pump track. We talked location and he said we have approval to build it right next to the trailhead, which would be beneficial for building and maintaining it and would also be a nice warmup spot while waiting for other riders, etc. etc. The corp will be providing as much dirt as we need, we just need the manpower to create this thing.
If you are interested in helping out please post up here so I can gauge the interest in the pumptrack itself and how many might be interested in picking up a shovel and helping out!
