Would be more mindful of the winds at that time of year. Banning Pass with a Santa Ana blowing can be quite testy, as can trying to sneak over the mountain tops because you don't have O2 or excess performance. Not neccessarily dangerous, just very unpleasant.

Oh yea, I know the famous Banning Pass ;) One of my QXC's for the PPL was to Palm Springs on a hot summer's day. Best stay high, 11.5k min through there....
