Neighbor is a sometimes rider who wanted to do something on pavement. Maybe on Beach Drive (for you non-DCers, the road that follows Rock Creek and is a favorite for folks who live in DC to get "road" miles), he said, as it's been awhile since he rode there. To DC, he was asked? Welllll, maybe not TOO many miles. Alllllrighty then, Goldilocks, here we go. There's this nice section mostly closed to cars, then it's a commuter route and we have get on paved trails. Then we add some miles by going down to the 14th St Bridge (also famous for the Air Florida crash in 1982), then north by the Iwo Jima memorial and back across the river on the Key Bridge. From there, the long rail-grade climb up the Capital Crescent Trail. Felt a lot better than expected for riding consecutive days. Could have easily done 30+ as the contact points were not complaining at all. Neighbor (less than half my age) said he coulda gone more. Alas, he rode behind the whole time and the old guy got zero benefit from the testosterone wafting back...
