We did it!Yea.
From the Dead End of North Frontage Road to the cross roads in front of Telegraph Pass it took about 13 minutes. It is about 3/4 of a mile.
From there to the top, (the bench in front of the towers) it took about 22 minutes. That includes 5 cigarette breaks. It is about a mile as a crow flies.
From the top back to the crossroads it took 9 minutes.
Then from that point to where we parked our trucks and cars it took about 8 minutes.
Now, granted at each point we waited for everyone to get there before doing each trek. There were about 4 people ahead of me, 2 with me, and the rest were behind. The times are my times for each distance. The whole time that elapsed was about 2 hours. Not too bad I was expecting about 3 and 1/2 hours. It was a good last PT for me.
