Dig by our apartment complex

There's supposedly "construction" going on right next to our apartment building. My theory is that they are actually doing an archaeological dig...at least prior to any construction, to make sure they are not building on anything ancient that needs to be preserved. Because you never know when something old is gonna turn up that hasn't yet been discovered. See the guys laying down? It's 10 am! The worst part is, around here, the guys pee out in the open all the time. And the spot where these guys are laying is the same area where the workers walk over to to pee. There are porta-potties on site that are never used.
