Mathew Mooty, Ameya Kanitkar, Tamar Melman, Brendan Ryan, and I departed for hiking at McConnells Mill State Park at noon on Sunday. Amy and Lux also set off for the park to do some climbing. After the hour drive, we began the hike at the mill under a sunny blue sky with a temperature in the low 80s. After hiking along the Gorge Trail for a few hours, we stopped for lunch on a large rock next to Slippery Rock Creek. Before heading back, we took advantage of a nice section of the creek to skip some rocks and discuss the merits of rock skipping as a competitive sport. At the end of the hike we ran into Lux and Amy, back from climbing. Back at the mill we watched some kayakers fool around above the waterfall before returning to Pittsburgh.
