It doesn't surprise me that the "bell" topic came up on a whistle thread,
as both of those only work if "you" believe in them
I have a friend who after riding many years and hundreds of thousands of miles,
installed a set of deer whistles on his bike, a week later he "hit a deer"
He'll tell you them whistles are dangerous and attract deer,
What I don't understand about the "demon" bell superstision is,
there are some of "you guys" who don't believe in a God,
but you'll believe in a bell?
I've been fortunate and have never hit a deer,
however I have hit a pheasant, rabbit, dog, turkey vulture and last year an Elk,
There's just not enough room to put all those different types of whistles on my bike.
