Games of Tags

you know, when they told you to "go and play in traffic" they weren't actually suggesting you do so...

this idea is an accident waiting to happen.

You limit the accidents by not making it a speed contest but about the joy of the game dude. Usually done in sunday morning away from core traffic. With all routes to check points accessable via less busy roads
1 percent was the one of the first groups to include non - working messengers in the game. One strong rider street rider with one not so savy rider work as a team, each "check point" is a treasure hunt where you have to perform an action or find the treasure specified.
There's no prize for 1st, so no incentive to do dumb stuff. The emphasis is on having fun not being fast. Last time me and my rookie went to a gallery and stopped for lunch before arriving at the end. He had a blast, had never ridden in london before and ended up buying a bike.

So, really my point is you may have some misconceptions about what an alley cat is.. some are for people with skills and those are not generally for common consumption, but in actuality are no more dangerous than what those riders encounter every day - in their working life.
Some, are meant to be social fun and encourage and improve riding.
The latter is what i am talking about.
