The Catalyst development started coming alive earlier this week, and today marks the first day of real significant activity since the pile drill showed up. The perimeter fence was extended on Monday / Tuesday, and today the entire lot was milled and cleared. We can expect to see the pile borer start moving about the site very soon I think. It is currently parked out of site to the left of these images.
As an added bonus, you can see the Kalamazoo Ribfest ramping up in the distance.
