I have every sympathy for you, it's bad enough witnessing it as a passenger, never mind being the driver.
I used to go out with a girl who lived in a "slightly" dodgy area of Glasgow. The bus route to her house took us through the few areas that were actually worse than hers. Every saturday night, without fail, the bus would get bricked.
The slightly bizarre thing about it was seeing what new and ingenious ways the toe-rags could think of to attack the bus.
The highlight (or lowlight) had to be the week they had manufactured a catapult out of some oil drums, scaffolding and planks of wood. It was like something Wyle E Coyote would use against road runner. They had a plank of wood sitting over the drums see-saw style, and two of them leapt off the scaffolding onto the plank, propelling the rocks that were sitting at the other end of the plank hopefully bus-wards. I thought it would never work and at best they'd clonk themselves with the rocks. However, while I laughed at the sheer surrealism of it they managed a direct hit with a bloody great boulder from fully 50 yards which nearly went clean through the bus.
Only thing more bizarre was the pregnant woman sitting opposite us who breifly looked up, went "tch" and carried on reading her mag. Obviously battle hardened.
There's a blog from a Glasgow bus driver on the web which is pretty entertaining reading, I'm sure a lot of you have seen it. Think it's
