I was wondering where all the visitors were coming from!

I've skied Shasta twice. The
Hotlum-Wintun Ridge trip was July 20, 2005 (a big snow year!).
The
Avalanche Gulch trip was July 1, 2006.
I do recommend Shasta - it's a very different mountain (and experience) from Whitney.
Glad you enjoyed the PCT report. Bill was a great hiking partner (except his pack weighed less than mine).
