Went out to Labcorp for a 9:25 appt for blood testing. When I got back I mounted Jacks hard drive into one of my aluminum cases. I also tried to disassemble his laptop and diagnose the problem with the battery charging. His laptop won't charge the battery anymore. Best Buy said the power jack was bad. I found it was good but since wires from the jack go to the motherboard I surmised the motherboard circuitry is at fault. In the PM we had to repair one of the shelves on the tower which had sprung a leak. We went to the greenhouse and got some poly which we cut into a 4x8 and lined the shelf before putting down the mats. It seemed to work well. I need to purchase a 4x8 sheet of plywood and some 1x2s to coat another shelf with resin. After a yummy dinner of Meyer lemon chicken we went to the group class at 7:15. We lucked out since we were the only ones who showed up so we essentially had a private lesson with Erica learning a few more steps to the Salsa. I felt good about the lesson but we need some music at home to practice to. We did the dance party afterwards and lasted from 8:00 to 9:15. I'm not sure how long the party goes on. I'm pretty happy with our progress in ballroom techniques to date.
