I played in a co-ed soccer league, but stopped playing a few years back. Every player was drafted/assigned based upon ability and you could only request to play with one other person (keep the husband and wives together). We kept score, but there were no standings, playoffs etc.. At least 3 women (which could include guys over 50) had to be on the field at all times. No slide tackles. Red card for hat trick etc..
Namby pamby as Hell, but I liked it. I'm done with ultra competitive sports (played in college) and just want to have a good time, hit the ball around, and get some exercise. In spite of all this, I got really tired of mid-life crisis agro-dicks running around like idiots, not passing to the women, screaming at the ref, clipping my ankles, or purposely matching up with women to gain an advantage. WTF dude - go play with the mexicans in the park if you want to get in fistfights and be a dick. The final straw was this idiot who slid into a keeper late and broke his leg a few years back. The keeper wasn't a player - he was just there to have a good time and this guy just wrecked him.
