5/27/22 - So I decided I did not want to drill holes through the joists for running wires. Instead I used a pair PVC pipe hangers screwed to each joist. I'm not sure there is really any advantage to this method, but we'll see.
I also picked up my Homasote (at $40. a sheet ). I got that cut up and painted. I found a gallon of oops paint at Lowes called Milk Chocolate. Talk about perfect timing. The Homasote is now installed and I will be getting my track order shortly.
