Scooter Polo

File this one under "Crazy and/or Silly Ideas". I was hanging out with some of my girlfriend's friends and, I don't know how we got on the subject, but I suddenly developed a huge urge to conceptualize and play Scooter Polo. That is, a game similar to polo, but on manual scooters (like the Razor that was popular a few years ago, not the electric or motor ones, the ones that little kids can use). Somehow we were talking about playing a random game together and someone brought up polo. Unfortunately, none of us had horses. There is a variation involving Segways, but we didn't have any of those either. But the discussion did make me think about scooters. I didn't have a scooter myself, but a few of my friends and my girlfriend has one and I sometimes liked to have fun on them (kind of makes me think about the Mazda zoom zoom concept).

The next day, while shopping at a sports store, I noticed a croquet set and scooters on sale. I didn't buy them, but it did make me think and re-invigorated my interest in a scooter variation of polo. So, here we go:

Scooter Polo
Currently this game is designed for recreation. Thus, rules are informal and players should make sure that anything vague is clarified or modified accordingly.

Set up
4 vs. 4 or 3 vs. 3, no goalies
Played in an enclosed space, like a roller hockey rink, with boundaries boarded so that the ball doesn’t go out of bounds, but instead bounces back.
Goal
The goal is the same as a hockey net, including the crease
You may pass through the crease, but must maintain constant forward motion. Additionally, your feet cannot touch down inside the crease.
Equipment
Each player should have an arm length mallet and a scooter. There are no real protective equipment, but closed toe shoes are strongly recommended. If possible, players should all use similar equipment. I recommend standard croquet mallets and average to economy standard scooters.
The goal does not need a net and can be marked by anything. The crease should be noted in some fashion.
The ball can be anything spherical, a roller hockey ball or a croquet ball would suffice.

Moving the Ball
You can only hit the ball with a full swing (starting with the mallet straight up and swinging 180 degrees to hit the ball) and when both feet are on the scooter.
Goals can only be scored by legal hits of the ball
The mallet can only touch the ball, but the ball can be touched by mallets and scooters, but not feet or other body parts.
If the ball is airborne, it may be knocked down in any manner, provided that it is knocked down immediately with the first contact.
Other rules
As this is a recreational sport, bodily contact is prohibited. It is considered good sportsmanship to be moving primarily laterally between the two goals, moving horizontally across the play area should typically be only done when changing directions. This should prevent accidental collisions.

Well, that's all I can think about currently in terms of rules. Most other things are similar to polo, or can be covered with house rules. If there is anything that you think I should address, let me know.
