Thanks NY Dan,
The perspective helps as I was trying to get a RIM2RIM2RIM kicked off the end of this month, but its not looking likely as the North RIM closure is just so variable right now.
I too turned away around a 1000 feet or so short on my first attempt at C2C (the one I said took 18 hours), only we turned away around 6pm, and had to hustle to make the tram. For us it was partially conditioning as my brother in law was struggling, so we took lots of time doing things like spending an hour looking for someone geocache, hanging out at flatrock, etc.
But we came back the next two years and made it to the summit.
Yes, a space blanket and then some. All three times we have been the last people on the tram side of the mountain, in the dark and cold. The two summits we met one guy with a dog each time (what is that all about) but they headed down the summit to Idyewild, so we headed down and did not see a soul until the tram. As you noted its cold up there in October/November - I would hate to twist an ankle coming off the summit in the wind and cold I always encounter and not be prepared.
Thanks for the trip report, hopefully you will be back. I find it easy to come up with reasons to visit Palm Springs, mostly because I was born and raised there

, but even if I wasnt, the SUN is a good enough reason
