I got knocked right off my bike last weekend. Was on a multi use path on the right hand side, wasn't busy. A younger guy (late teens/early 20s maybe) comes up from over a small hill, earphones in, not paying attention to what he was doing at all, along the middle of the path. I saw him and pulled as far to the right as I possibly could and he kept going to his left. He ended up crashing into my front wheel, fairly hard, and I landed under my bike, in the bushes, my hair was FULL of burrs. He apologized and checked if I was ok (I was fine, just angry) and then continued on. If he'd been that distracted driving a car on the road it would have been a serious collision.
