Kevin, that's a great site - very educational. I had no clue such ferocious winds were common on Shasta. I have a buddy who is a Marine Recon mountaineering instructor, and he typically makes a couple of trips a year to climb Shasta with some of his trainees. He's never mentioned the wind being such an issue - but then again, he's a Marine and would never admit to a hardship in the first place.
It is a good site, and Shasta is fortunate to have snow rangers who've worked on the mountain for several years. They're friendly and competent. An additional benefit of that USFS district is that staff manning the permit desk actually climb the mountain regularly, so if you stop by before a climb to get the latest beta, it's often first-hand and detailed.
After all, if you had a good job in Mt Shasta, would you EVER move?!
