This one is called the Great Schools website: http://www.greatschools.net/
.......has detailed information regarding schools and even has a place where consumers can leave comments about their personal experience regarding an individual school. The Idyllwild Arts Academy has a high rating. I personally have always liked Idyllwild because of it's mountain and small town feel, but this is my personal opinion.
Regarding the gangs from Hemet the best thing to do is go there and ask the local business owners. Also, I am sure there is some kind of neighborhood watch group than can help.
Good luck and let us know what you think or find out! :)
As far as a safe community, I would choose to live no where else in So. CA. We all tend to look out for each other and the beautiful thing is that there is a deep sense of community here, making it some much more unique than so many other communities in So. CA.
I have several friends who have their children attending Idyllwild Arts and it is an amazing school. Truly, although I am not aware of other simialr schools throughout the country, I can say that Idyllwild is a community that will touch your heart with warmth and kindness. When my family comes to visit from back east, they continue to comment about how everyone is "so friendly."
Wouldn't choose to live anywhere else!
Also, know that I am a realtor and would be glad to help with not only a possible purchase, but also if you're in need of a rental or any other information that might help with your decision making process about this wonderful mountain town.
I recommend Idyllwild to anyone. I have great memories.
