Yes rstofer, silicon 'Valley' has all those special housing and freeway congestion issues, to the point now, that literally EVERYONE seems to move eastward, towards Nevada State, creating a weird 'infill' pattern in the Calif. Central valley. That soil-rich region was supposed to be providing food / agriculture.
Many old friends, retired and moved (away), as I sit, unemployed, approx. 20 miles from the whole, Sunnyvale, Santa Clara city areas (where Intel and various aurospace companies did military or NASA projects.
Funny thing, many jobs have evaporated, but not traffic congestion. Traffic congestion, you've got a salary related factor right there, (due to significant stretches of daily time spent).
