I'm in austin, but I keep wishing that I lived in Silicon Valley or PNW - namely due to:
* greater ability to commute by bicycle/train/public transit. Austin's bicycle scene is growing, but it's still fairly impractical due to the lack of public transit infrastructure.
* potential for more outdoor trips - hiking around austin is fun when there's water around, but we easily have drought years too which aren't as fun. Plus, I'd think planning a ski or surfing trip is much easier out west than here. Many of my valley friends afford to share a house in tahoe during the winter.
