Bobcat Jackhammer Attachment

Wednesday, April 22, 2009 was a beautifully sunny day in Minneapolis. This quarter my schedule includes a three hour break, which I usually use for catching up on curriculum, ACB entries or meeting with students, but this time I let Spring fever take hold and got on my bike a rode around one of my favorite city lakes. There’s a nice spot on the lake where I sometimes read or take an afternoon nap. Unfortunately just across the lake from my spot was a work crew using a jackhammer to break up a cement driveway. If you can’t beat ‘um, join ‘um right? Having my PCM-D50 along, I finally gave up on the idea of a few Zs and rode over to the action to make a recording. It took a minute to get the levels right, but I think they were going to be at it all day, so there was plenty of time for a good long recording. Here’s a few passes of the jackhammer engaged and splitting concrete.
