While you are frying your brain in 100+ degree weather, we'll be sending in the cool alpine air, far from the maddening throngs.
Have fun climbing at Charleston, I am sure drilled and chipped holds in 90 degree weather is just as good.
My friend Chris and I climbed that back in the early 90's just before they replaced the upside-down fixed pins in the quintuple roofs at the top with bolts.
Sketch-mo!
What a great route though, too bad the Lower is closed.
putting a notice up and checking the notes at the local climbing gyms is always a good idea.
Hang out at UW wall, be friendly and you'll meet some folks that will show you the area.
Good luck!
