Digging holes, windows

I was constructing two wooden boxes to hold the concrete for the sign and then I hear a crash!
Max and Jacek were taking off the metal guards on the windows and well it didn't go so well......
I started digging the holes down by the road to get ready for installation of the sign next week!
I was wondering a lot about how I'm going to get the sign to stay in the ground in fresh concrete without moving with it being so so windy here most days and the sign being a big flat piece of steel 5 feet in the air........
Then it hit me! Put two smaller pipes in the ground first secured well with lots of concrete and then slide the sign onto the pipes!
Genius!!!
