Never let online bullies/trolls psyche you into silence, and most of all into risking your life.
When I first started riding not long ago, and after suffering near life ending, and crippling injuries, after having been hit and run over by a vehicle traveling at a high rate of speed, which left me crippled and living in a convalescent hospital for some time. I was sure I'd be spending as many of my ride miles as possible on the sidewalk. Once I was in better shape, and was finally able to begin riding a bit, I quickly realized how many problems come along with trying to ride on sidewalks most of the time. So, after putting in some miles riding, I definitely prefer the street for a lot of reasons everyone already knows, but of course I "will" get up on the sidewalk if the situation I'm in makes that the safer option.
