We live in a small subdivision (just 4 streets) in an older neighborhood. It's ranch houses for the most part, with large 1/2 acre plots. We're on a corner so we have almost an acre. Some folks don't keep up their yards as well as others, but there are no eyesores.....EXCEPT for our neighbor.

It's a rental, and the people before them kept it very neat and tidy. These folks have trash spilling out of the trash bins, random stuff littering the front yard, there is an inspirational truck AND a boat in the driveway with parts and tools and detritus everywhere. The back yard has a swing set that is also broken, toys and bikes and a plastic playhouse for their 8 year old girl all randomly scattered and in various states of disrepair. The worst is the dogs. They have 4 and there are holes and toys and broken dog houses, and the POOP SMELL!!!
There is only chain link fencing (theirs) separating the yards, so we've started planting small, fast trowing trees in one section, and Ron's in the process of making a fence for the other section. It won't handle the smell, but it will at least mean we don't have to look at the mess every time we're outside. And also hopefully prevent the dogs seeing us when we're out, because they bark non stop.
