Great write-up. And congrats on finishing. Good job.
By the way, the water at the Grapevine Ranger Station was a stand alone faucet five feet from the west side of the rode along side the ticket booth. I made the same mistake last year and dried out badly in both directions. This year I asked one of the people seeking shade under the information center and they pointed it out. (Google Street View:
That little waist high stump next to the sidewalk is the faucet.)
I put my double write-up
here if you're interested.
Come on out and do the Spring version. Lots more rollers, a bigger climb and even lower below sea level.
