Flabob (RIR). Home of EAA Chapter 1. Interesting little airport. Plan on having breakfast at the restaurant. Just east of Chino (CNO), where there is a great aviation museum and Flo's restaurant.
For the Palm Springs (PSP) area, I would recommend Bermuda Dunes (UDD) instead of PSP itself. More friendly to smaller aircraft, including corporate, who many go to Jackie Cochran (TRM). On the way, make a stop at Banning (BNG), but check the wind first. You see what I mean when you get there.
Big Bear (L35) at 6752' isn't very suitable for a C150/152.
Camarillo (CMA) has a CAF squadron and museum, which is worth the see.
Should be fun.
