Cycling on ice... a guide

i've been well careful of the ice and then i came off on corner of ceceilia road last night and broke my arm and there was no ice to be found!

don't get it - water on the ground? i guess rear wheel would give when cornering in which case would bigger tyres be better? gatorskin on rear which i've always found ok.

Scaphoid fracture? I have just had my plaster removed after falling hard a month or so ago on ice. Don't lean - good advice.
