Why not fit dogs with bells so you can hear them when they come chaseing after you.
Strangely dogs are like women,can always keep yapping at you even when chaseing you down the road,well the ex did.
TJ's perfect world must stop somewhere around Birmingham, then. I have bells on all my bikes, and I use them all the time, as a Sustrans Ranger I'm pretty much obliged to. I've lost count of the number of times I've had aggressive reactions from walkers and dog walkers on shared-use paths, and even country roads. People regularly stop and look around their feet when I ring my bell, ignore it, tell me I have to get off and push my bike past people with dogs, (yes, really), complain because I [i]do[/i] ring a bell, I've had a girl on a phone suddenly walk in front of me after I rang my bell to let her know I was there, knocking me clean off my bike. Fortunately, she fell over too and smashed her bloody phone on the ground. I pleased for you, TJ, that your world is such a perfect place, some of us have to live in a real one.
