I just got back from the ride. It was 480 miles total over saturday and sunday. Everything went well if you ignore the all day rain on sunday.
State route 148 - excellent
State route 26 - twisty, very twisty
State route 800 - excellent. Crooked enough to have fun, straight enough to be rideable.
State route 78 - excellent
State route 255 - stay off. Gravel, sharp curves, bad blacktop.
