Had a near-perfect ride on the 4th of July: 107 miles, 9.8K of climbing, on some fabulous roads.

I started at the entrance to Skyline Drive at Shenandoah NP, but headed back east going through Flint Hill, Orlean, Amissville, Boston, Sperryville, and finally back the last 30x miles on Skyine Drive to the start point. The weather was just interesting enough, but not too interesting. I got showered on a couple of times on the climb up from Sperryville into SNP, and also on the uphill on Hogback, but never got completely soaked, so it was refreshing but not dangerous or unpleasant.
