I did the B-B-B yesterday too.
One of our group wasn't up to doing the century so we did the 68.
You're description is right on the money. Great ride with a few poor markings that boosted our miles to about 75.
Just the right stuff at the rest stops.
Definetly a repeat every year.

btw ... that guy you helped..sounds like he had a mild stroke.
Good deed, indeed.
