Hmm, I'll send him an email since I wiped out there.
Slightly off topic, but so far this week I only commuted on Monday (7/6) and Thursday (7/9). I noticed that sometime between these days the Custis Trail from Spout Run east about for about 1/3 mile was repaved!!! This was one of the worst stretches in terms of trail quality so the repaving is awesome. Enjoy the smooth ride, no more posterior lifting.
