(Inge, do these times make sense to you?)
Pin-Pin, speaking for myself I would figure (guess) on 1:10 from the trailhead to the trail to Allen. That’s based on my estimate of 5 miles and ''trail'' conditions. The 2 mi. to Skylight Brook would take me about 50 min. round trip (2 mi. 500 feet elev. gain and loss) That makes for about 3:15 round trip given decent trail conditions and leaves 2:15 to go up and down Allen and its 2000 feet of vertical. I don’t think I could do it, more like 3 hours in my case which makes for a time of 6:15 which seems pretty slow by your standards. I guess if anybody can do it in under 5:30 it’s you. Perhaps in the future people will refer to their trip times in Pin-Pin units. ''Oh, we made good time, it only took us 1½ Pin-Pin units.''
