I was out testing this past week, at a great site. Unfortunately, it was very difficult to work in the office that we were allotted. The building was undergoing massive renovation, and our office seemed like the hub of network activity. When the workers were not stringing CAT 6 cable, there was constant drilling; putting dust everywhere. And, if that wasn't enough, the fire alarm went off in the middle of running some tests. There's nothing like a high ranking officer kicking you out of the building, into the cold, with active tests running.
Moments later, the fire department gave us the all-clear to return.
