16 miles yesterday, we went north from Harper's Ferry to Rocky Run shelter. Great practice run and our highest mileage day yet! The last hour or two were aided by our headlamps (*love* the Gizmo's adjustable brightness!), a real benefit! We would otherwise have had to stop much earlier at Crampton's Gap, or found a random place to camp midway (didn't particularly want to as it was raining). Either would have made today's hike back to the car longer. It felt great rolling in to the shelter at 10pm feeling unstoppable and then crashing for the night. The headlamps will definitely be a permanent part of our gear! P.S. Lithium batteries weigh less and last longer!
