Today J.B. worked on some welding on the new raceway that leads to Young’s Hill. Recently Jackie wrote about how it seems that the chimps definitely know what’s been going on the last few months, and mentions that J.B. watched Jamie try to get his attention and pull on the door a little, too. You’ll see some of that in this video. We are lucky to have such great quality control around here–Jamie is always making sure we did a good enough job!
