Map Trash Cleanup! v 0.2 This mod removes the spilled cans and tires near the trailer. I did this by editing the town layout in Town.xnb. I suspect that it may work during all seasons, but I have only been able to test Spring.

My only particular complaint about this mod is that while it removes the trash in the base town map, it returns for events that take place in the town (like the egg hunt in Spring, for example). Aside from that, it's working perfectly, and handles a minor grump I had about town map from the start--that being that you couldn't clean up the trash.
