I live next to a MUP that runs primarily through the undeveloped desert. It is nice to use this MUP becasue it leads to roads farther away from the city. There is little traffic on this path, (unlike the urban MUPs in town) and once I am off the MUP the roads open up and don't have traffic lights.
The problem is that the MUP has lots of rocks on it especially on the corners due to ATV/dirt bike users, despite signs posted restricting motorized vehicles. Since the trail is on BLM land the city and county can't (won't?) enforce the rules or clean the path.
Instead of (only) complaining I am trying to be part of the solution. I would like to buy/build a tow-behind sweeper that I could bring on the path to sweep away the rocks. I have found a few sweepers that are designed to tow behind a lawn mower, but these are for picking up leaves, not knocking rocks off a path. I think a simple design of dragging a section of chain link fence, similar to a groundskeeper's tool for a baseball infield might work, but I don't want to simply drag the rocks farther I want to knock them off the path entirely. Perhaps if I put an angled leading edge on the chain linked fence the rocks would deflect off? Will draging an apparatus like this damage the asphalt surface of the trail?
I am looking for suggestions or better ideas here.
