This is Dad’s dog fence.
There are neighbor dogs who used to come into the garage and pee on things. There was a construction project and Dad saw this netting and had an idea. There were some steps involved to get Dad the netting. It involved a former federal highways employee and a tribal official. We are related to these people.
I wish I got a better picture because Dad rigged this so it will attach to the existing garage door frame. Then roll back for storage.
And, keeps the dogs out.
