On Monday, some new "boxes" sprouted up behind the Elementary school....

By Thursday, they were digging large holes in the ground for gas and electricity, and ???



These guys looked like they knew what they were doing. The electricity was turned off in the Elementary school for a while and they were working over time (past 5:00 pm anyway) to get it turned back on.

(Note the big hole)

The view behind the Elementary school is a little bit different these days...





and they're leaving secret codes on the sidewalk!

what do you think THAT means?
