This thread got me thinking that wouldn't all of the metal garbage and glass cause problems in the rain? I wouldn't be able to see it well, especially if it were submerged, and I swerve around a fair bit of it on the shoulders of the two highways I traverse. I ride in the shoulders because I'm not about to get in a lane with a car doing 55+ MPH. I've been thinking about stopping to move it further away from the road, and even carrying a hand broom to sweep away piles of broken glass. I think I may start to pick up one item/pile per day and get it out of the way. I wonder if that will be enough... lately the amount of it seems to have gotten exponentially higher.
