This summer. From home in Alexandria, VA to Harpers Ferry, WV on the C&O and back on C&O and W&OD. 75 miles each day. This was the weekend when DC's summer heat wave maxed out. 100+ in the sun. 80 degrees at night. Camped out at a hiker biker site near HF. CGOAB journal here:

Not sure when my next tour, even overnighter, is going to be. Baby coming in April, so I'll probably be busy getting used to the dad thing next summer...
