Dad came back for a couple of hours this afternoon, and finished the shed. Yippee yahoo!
The ramp is fixed (it now reaches the ground!) and the windows are insulated around with spray foam (not for insulation value, since the shed is unheated, but to keep the critters out - there was a lot of space around the windows).
The cross ties are up, which gives me a dandy overhead storage space for leftover wood (as well as proving a bit more structural strength).
And there is less leftover wood, as I talked Dad into building me a small workbench with some of it - thanks Dad!!
As for pictures - as soon as I get it organized, I'll take and post them!
