Well lucky the builder put up a fence in the rear for the house behind me and also for the house on the west side so I only have one side to build and its like 40' long is all. I can and used to do this all myself but after my surgery I just don't have the ability to lift much (Dr. said nothing over 20 lbs) and I think a post hole digger full of dirt is pushing the limit and I know bags of concrete mix is way too much. I've been contemplating paying someone to build it, but...
Yeah, was going to help my father do something similar at his place. His wife didn't want me coming out around Christmas time to help get it done because that was his vacation. Ended up not going and a few months later he fell and was hurt so he ended up having to pay someone. But like I said if a few of us all get together pretty much any job can be tackled even if a bunch of us are only partly useful.
As far as a supervisor I have my own clipboard and I am sure I can find a whistle somewhere.... Then again maybe a starter pistol to keep in line with the site. Get some of those really hot 22 blanks from the hardware store and.... Well maybe not someone is bound to call the cops.
