Spotted...

I've had one hit me in the forehead once, it felt like a soft tennisball, but a bit bigger... Hopped up a kerb and made it shit itself, i ducked but it still hit me.

Haha. I had one fly into my front wheel once. it got stuck in the spoke's(it was on a mountain bike so had wide forks) went round a couple of times then got shot out like a bullet, it was very funny till I came to cleaning my bike. Those fuckers are filthy!
