Not for your trip out west, but back on the East Coast here's an offbeat suggestion:
Franklin W. Olin College of Engineering
The place is only six years old and is tiny: about 300 students in the entire school.
But it is serious: 10.5% admit rate; mid-50% SATs of 2150-2310 (Class of 2011), which compares pretty well with Caltech: 17%; 2190-2320.
For the right kind of kid, it could be great (my D has a friend -- a Presidential Scholar -- who is currently a sophomore there and is head over heels about it).
Oh yeah, one other thing: Every student gets full tuition for four years.
