Vertigo is one of the prime precursors when living in CA!!!! I do not mention it often because it does not happen much up here, but in the Bay Area it really bugs me! I don't know what I would do without Jane in some of these instances...Support is VERY important and it sounds like Don is a great companion with mucho knowledge....I envy him..

Last two times I had a serious vertigo problem was when I was on Telegraph at Shattuck where the old Co-op used to be..Last I was there it was a trendy type co-op... anyway had serious vertigo problems at that location before the Richmond quake in 93 and one more which I lost due to the HD crash....Telegraph from Shattuck all the way to Sader Gate at CAL, is a very powerful area... No words can describe it, but people who frequent the area know that it has been this way since..
Many do NOT know however because it is impossible to get a parking space within 5 miles:-)
