I got married at 30... I thought I was too young.
However, I would hate to be single again, that whole scene sucks... except for the poon variety.
Just be sure to marry a "wife", and not a "girlfriend." By that I mean, I have dated some down chicks in my life, but would never trust them to be a good Mother, or loyal for a lifetime. Don't marry the female version of yourself, it will never work out in the long run. You need someone with differences so you can learn from each other and never get bored with the same old everything.
I found a nice midwestern girl who loves beer, football(all other sports too, which is key) & poker, so I'm set.
