I ride alone, I live in the burbs of Southern Ca.

I ride in areas that are heavily residential. However because it is the burbs, Lots of gas stations are close by. I bring my cell with me and other 'emergency' items, bike tools, bandaids etc. I know how to change a flat. Don't usually have a problem.

Learn how to change a flat tire.

I also have 2 or 3 common routes that I share with my family. (Cuz they all think I'm gonna die out there!)

I have a regular departure time and a regular return time.

On weekends I ride farther and longer and many times call them when I'm at the point of turning around and going home. This helps cuz they will sometimes call me if I'm gone too long.

The key is to enjoy yourself.
