Sorry to hear about your mate Mig, TBH I never knew about your accident. Honestly I don't see the chair just a really nice guy with a love of life matey:D
It sucks it really does, anyone one who rides or used to would have lost people close to them. Then again I lost a few friends in car wrecks, especially when we were younger. I know everytime I go out on the bike I risk losing my life but the pleasure it gives me and the friends it has brought into my life, its a risk I take. Thankfully I have never knocked anyone off a bike whilst driving the car but it can happen, we all have lack of judgement sometimes, its just more fatal when it involves a bike:(
