Folks that blast IE as being "the worst" often never lived here. Just like any other county, its got good and bad. People that live in national city claim to be from SD but reality is, I wouldn't live there. Hell, OC even has garden grove. ;-)
Just do some research, call some depts, etc. Riverside county does get warm but I'm from Phoenix so not a big deal to me. In exchange for high temps you get lower cost of living (rent/mortgage, gas, etc). Nicer areas include Rancho Cucamonga, Corona, Temecula. You can do OC but your paycheck doesn't go as far. For every wealthy resident, there's many more people that are "ghetto fab". They spend so much on housing and trying to look better off that they're always broke. However, there are areas that are somewhat reasonable (for OC). Check out the somewhat inland areas of Anaheim, Orange, Fullerton, etc.
Good luck to ya. Hope you get hired on soon. LOTS of tight budgets out there. A friend is trying for Laguna....ONE opening.
Always follow a great leader. In the absence of a great leader, BE ONE.
