Overnighter from route 653 trailhead to Grindle Ridge shelters on Laurel Highlands Hiking Trail. 6.5 miles each way. Learned that the trail map icon for water means potable only, but there are actual pumps at the shelter sites that you can treat. I didn't realize this, so I was PRETTY THIRSTY BEING ALL CONSERVE-Y.
