I plan on doing model railroad eventually.
Last weekend I cleaned most of the junk off the top of it, and I'll eventually get around to dismantling it. I came up with a plan that fits on a 30" x 80" door (I model in N scale, btw) and offers plenty for operations. But first, I have to get the old layout out of the way...
And for what it's worth, the impetus to start a new layout came when I found this up for sale on eBay.
