Weeding down the line

As long as daylight savings time holds out, I've been spending evenings after work gradually removing Natal grass and other weeds from the main north-south path.

I notice the contractors have been in, but the only evidence of work I've seen has been the herbiciding of plants OUTSIDE the fence. It's helpful, but I don't get it.

I've also launched a search for trash along that section of fence to clean things up a bit, since the neighbors (some of them anyway) continue to dump there. A lot of it's paleotrash, such as the steel soft drink cans.

There are several tires, too. I'm not sure what to do about them except pile them in the right of way.
