I was on one of the construction sites for the Sound Transit expansion to Federal Way. As I walked around the parking garage that was under construction, I came across a piece of equipment I had not seen before. I have seen machines for working the surface of concrete before but this one has two rotating elements under a seat. The operator rides on the machine. It looks like some kids version of a jet pack.
The better news was that a second one was in use on the upper levels of the parking structure. When I got up the tower crane, I was able to shoot a little video of it in use. It is a curious looking piece of machinery and, having never seen it before, seeing it in use really made me smile.
