Call Tehachapi Art Center, I believe one or more of thier artist have kids classes.  Sam loved Karate when he was younger, he was 7 or 8 at that time though, he and his sister Sarah were orange belts when they got bored with it. 

Maybe try mud hut if he is interested in painting. It's always neat to see how kids paint their own ceramics. I think they still have preschool (though even my older kids still love to be read to) reading time at the library once or twice a week, but you might want to check on that one. Also, check with parks & rec. They do have a soccer in the fall if he's interested in that, as does ayso. Good luck!

My son is also 5 -- will be 6 in February. He took a clay class at the Art Center and really enjoyed it. I was worried it would be too 'old' for him, but they held his attention and he made a neat picture frame.  My son also enjoyed the Mud Hut.  

A whole new world is going to open up for him in kindergarden in a few weeks, so you might wait and see what interests him at school.... and not overwhelm him with a lot of new things going on at once.....

You may try other martial arts, such as Tae Kwon Do.   Tae kwon Do is all about control, violence is very discouraged, even in competition...if that's what you are worried about. 

But I also agree with Sunshine that maybe you should wait to see what he's interested in.    And remember, kids get "bored" at the drop of a hat, so even if they love something they may say they want to quit on a bad day.  Also, I see way too many kids that are OVER-involved, even before they hit high school.  Help him find something he loves and encourage it, but don't push him into anything.

Mimi- He's already enrolled in AYSO. We did T-ball this spring also. I'm just looking for something more consistent. Our daughter dances once a week. Pretty much just trying to keep it fair, and give him some options. He really enjoys riding his bike too. We just moved and have a huge lot. I'm thinking about getting the hubby to make him a mini bmx course.

 I think 7 or 8 would be a better age to start karate. Some people I've talked to just thought that it was a bit to intense for the younger ones. I probably should just see for myself.

Sunshine- he's really excited about school. He needs more interaction with kids his own age. We should get our boys together! Does your son like bmx? They could ride together.

Home Depot has a class of some kind that the kids can build different things.  One of the girls at work takes her kids there.  Try giving them a call and find out what the age limits are.  I'm not sure. (Just heard about it).   

Countygirl- we took the training wheels off on Easter Sunday.... but he is still not riding the 2 wheel bike. Maybe your son could teach and encourage him!!  I think he's given up. When I suggest we practice, he just wants to go back to the tricycle.
