The Potomac Appalachian Trail Club (PATC) used to host an event called the Dogwood 50K, and this was part of the course sometimes. I did this race in 1998 through 2002. It was always held toward the end of April. I've hiked up Signal Knob and Meneka Peak a few times since then, in various ways.
Signal Knob/Meneka Peak Date Climbed: Jul 28, 2011
Hiked the short version of the trail by returning to Meneka peak trail along the ridge. Trail was easy to follow, no one else was on the trail. Saw a timber rattler and two copperheads but no other interesting wildlife probably due to the pace, only stopped for a few picture/water breaks, started at 6p after work and was back to the car at 10p.
