For some, this may be a possibility. Have you ever watched where a street sweeper machine dumps the "Fines" and other debris when the hopper is full? Here where I live, the State come spring, will street sweep the highway shoulder/curb through town to clean up all the anti-skid or sand that was put out over winter. Instead of driving all the miles back to the State shed to empty it in the yard, they go a short distance out of town and dump it along the highway right of way. I'm told in some locations, after every snow storm has passed and all has melted on the road, the State is required to sweep as soon as possible through some cities. I guess some cities don't like the dust when anti-skid materials dry up.
I detected a pile I knew came from town last spring and found a few coins (pennies, dimes, quarters) and a chain with keys attached to it. Are the gears turning in your MD heads now?
Think of all the city streets and parking lots that get swept and where do they go to dump the hoppers. May not hurt to watch, follow, and or ask a City or County shop foreman where they dump and can you detect the pile???
