Spotted...

some dude right in front of me at mountpleasant on a baby blue powdercoated frame and bars taking a nosedive after his front wheel disappearing down a drain cover full of dirty water. blam! ow! ewww!

hope you're okay dude. sorry i didn't have any spare tubes on me.

I hate drains that seem to be designed for that. There's a Diagnol slitted drain cover in Vauxhall Bus station, that's inline with the exit from one of the cycleroute tunnels... The amount of cyclists I've seen come off there is shocking, and I've reported it to the council and London Buses, but still nothing has been done. Just turning it round the other way would stop a majority of the falls.
