It does get hot here (not going to lie about that

, but I lived in Corona before this and it was hot there too.
It depends on what kind of "action" you like. There is only one bar in all of Yorba Linda, but several restaurants. My husband and I tend to go to Downtown Brea straight up Imperial Hwy/Birch street when we want to get out (Taps, Yard House, Melting Pot, Improv, two 6 screen theaters, Starbucks, Cold Stone ect.) It's about a 10 minute drive from the center of town. I prefer the nightlife a little farther out because you don't have to worry about the issues of living near "teen hangouts" and as many drunk people driving through your neighborhood.
The schools here are the main reason we moved from Corona. We paid for private school here and now our three kids are in public school. I like the people here too. There are many "horse people" (friendly and down to earth) and lots of great community activities. I know the names of almost all the postal employees who work in our post office-the only one in Yorba Linda.
I could never figure out why Kerrigan Ranch has an HOA because as far as I know everyone mainatains their own property and there are no community pools, parks ect. within the development.
BTW We also love that we can leave for Vegas during non peak traffic times on the 91 (yes, they do exist-LOL) and be in Vegas in about 4 hours -husband has Prius so it's cheap)
