Coming from south-eastern US and visiting Mountain View / Palo Alto on business several times, the property valuations are amazing to me. Poorly maintained looking ranch homes with bad landscaping and giant Land Rovers, Porsches, Jags in the driveway or on the street. Downtown looks almost like my semi-rural hometown except there are full parking garages and you have to park under an over-pass. It's a weird place.
