I don't know how many minorities are at the school, i know there are some. There are some on the basketball team. The majority of the school will be white.
If he is a "hood" or "urban- styled dude and/or hasn't been around upper-class people, he might not fit in too well b/c most students, asidefrom some athletes, are local rich kids. The cities around Menlo Park are pretty rich, like Atherton, Woodside, Portola Valley, Palo Alto, etc. Predominatelywhite area.
The girls that I know that go there are attractive white girls with $$. I would say that he would get a good education there. Don't think there would bemany parties there b/c the student body is so small, but it's really close to Stanford so he could party there if he wanted to, or go up to SF or down toSan Jose.
Menlo Park is a smaller city, about 30,000 people I would say. High School sports are big in the area, M-A (Menlo-Atherton) usually has good teams and so doesMenlo School, which is a private HS located next to Menlo College.
LOL @ him wanting "coverage" there, Stanford is going to get the most coverage by far.
I hope this helps you/your boy out, if you have any other questions feel free to shoot me a PM.
