I'll put in a vote for Elsinore. I started going there with 35 jumps last summer. I learned a lot with their free Excel Camps once a month-Formation Diving. Also, never had any problem finding people and groups to jump with-nice, friendly jumpers there.
They usually have 2-3 planes operating on weekends and occasionally bring out the awesome Skyvan!
During the warm months, there is a danger of dust devils and very gusty winds, after about 1 pm, but I believe Perris has the same issues.
The view to the west is incredible-Pacific Ocean with Catalina & San Clemente Islands. View to the east of Mt. Baldy, Gorgonio, San Jacinto, plus, all the lakes below.
A & B licensed jumpers do have to land in the outer LZ, which is mainly dirt from July to November-Grass/weeds grow there during the rainy season.
