At that point, I was able to go ahead and put in the insulation and sheet rock. One weekend, Jim came up and helped get the countertop and sink in.
For the past two weekends, I've been doing the insulation and sheet rock - just Luke and me. It's tough work especially with the heat. At this point, nearly all the sheet rock is hung (but not taped). That really makes things feel more finished.
I'll only have one more weekend this summer to work on the cabin before I'll need to stick around home to wait for the arrival of our boy. It's been a big year!
