From the description of the litter, Mr Thompson, it certainly did not come from cyclists. We use re-usable bidons that we can put into our bottle cages. Lucozade would be far too fizzy to drink whilst cycling.

Much as I would rejoice to hear that Parris had been killed or severely disfigured by a car bomb (only joking), what really pisses me off is that the bigot has a point. Cyclists who throw plastic into hedges, even in the lanes around Parris' commuter village, should be ashamed of themselves. It's bad for the environment, and (even worse) damages other cyclists' ability to feel self-righteous.

This was a witty article which made me chuckle.

I commute to work every day by bicycle and I am secretary of our local cycle trail development organisation (www.haldonfreeride.co.uk). I have experienced piano wire being strung between trees and it is not a sensible thing to do, but the perpetrators in this instance (an elderly couple) were arrested and nobody thought it was a matter to be taken lightly.

My personal bug-bear is pedestrians with push-chairs in cycle lanes. Were I to laughingly comment that these fools who endanger their children in this manner deserve to be tied to a railway line then nobody would see this as an encouragement to murder, merely an exaggeration for effect.

A lot of people are being very silly about this - clearly nobody is actually advocating the garotting of pedal-pushers here, it's just a bit of fun.

Oh, and I do not drop litter.
