Part 141 school with a fleet of well maintianed aircraft and Commercial Instructors. They have a very strong safety culture unlike a lot of places I've seen in the US. Fresno is well positioned for both North and South California. I had a great time and towards the end I managed to fly off about 5 hours a day, so getting your 30 done will be no bother at all, especially at this time of year.
Stratocaster is right about the wx at the coast, but in the valley we had unresticted viz and clear skies every day. It was HOT though!
