Yes, but anything - anything at all - thrown
at a cyclist could lead to tragedy. I suppose, counting up, I've had the odd object thrown at me. I recall a glass of water recently (well, at least I hope it was water - I showered and changed as soon as I got home...
). And, a very long time ago, I had something which I think is called 'silly string', set off on me. It's that party toy, not the explosive type, but the aerosol liquid which sets into solid threads in mid-air: I think you know what I'm referring to. I suppose the perpetrator though 'it's just harmless fun'. If it had gone in my eyes, with me cycling at speed in traffic, it might have been a different story.
