Larry,
Drop by my house, I'll spot ya a frostie and steer you in the right direction.
You should consider:
Harrison:
The hot springs now have access and you will be able to camp on the beach of Harrison without permit. If you are camping mid week you will have the Beach to yourself. The hot Springs are a series of connected pools with feed from the mountain at about 80 degrees.
Whistler/Pemberton:
You can drive from Harrison to Pemberton and then Switchback through Whistler. You must take in Whistler for a night while here, the venue for the 2010 Olympics, Summertime you can get awesome deals on room rates. Tons of awesome Mountainbiking and fun bars.
I am sure the boys fro BC PNWX would love to show you around and play host. Most of the guys do not frequent XOC.
Let me know, Happy to help
Claus
