Noonmark before ice climbing? Screw that! Get something to eat on the ride up, stop at the rest area just before exit 30 to leave a donation (inspired by that eveil drug coffee), and get climbing.
Ever since I stopped to get something to drink at noonmark on a sunday afternoon and had to wait for 10 minutes for a lady to make an ice cream cone for the person in front of me, I'm all done with that place. Besides, nobody goes there anymore, it's always too crowded!
