The schools are different, but the differences may not be as stark as you suggest.
- Scripps is bordered on all sides by co-ed institutions, and classes and dining are co-ed. (as @VVsmom pointed out.)
- Claremont Colleges have over 9000 students.
- Claremont is in LA county (population 10M), and is a Metrolink stop.
- No snow in Claremont but snowy mountains (and skiing) are suprisingly close by.
