I think this is a bad place to ask such a question due to the high number of phony San Diego snobs who “contribute” to this forum.
IMO and based on my experience, Temecula is a great place to raise a family. In general Temecula has very good schools, great Fire and Police Departments and other support services.
Temecula is a well run city, period. It’s not perfect, but pretty close.
I feel very privledged to live in Temecula.
Does Temecula have crime? Yes, unfortunately – much of it from people that do not live in Temecula. I’ll guarantee you this – while I do consider the Temecula police department fair – most citizens in Temecula (and the police department) will not put up with a whole lot of BS.
