So our yard is huge. We have a privacy fence all the way around. Except for one little area. It hasn't been a big deal, but we do look into our neighbors driveway/storage area (and they look into our yard when they're back there I guess). My solution: put some cool doors back there. I found some cool doors on craigslist. These are heavy doors from the Rocky Mountain Seed Company.
I nailed tin cans (thanks to the lunch lady at my school) with succulents planted in them to the door.
