The value is gone from baseball cards, right? I should just toss 'em or let them sit in boxes, right? Nah, blow more dough on them. A few months ago I bought a bunch of 9 pocket sheets to put them in binders rather than just storing them in boxes. This week I decided that was enough so I blew a little more dough on some acrylic card holders to display the best cards (hall of famers and favorites) in my loft book case. Pretty excited to finish out this project. For years they've just been sitting in boxes, now I'll walk by them every day and can easily stop and view them. It's almost better that they have little value. For a few years I was almost paranoid and kept the most valuable ones in my lock box. Now that I know nobody will break into my house for them, I feel good about having them out in the open.
Hobby #2, model trains. Years ago my son and I set up a nice U-shaped layout with 3 4x8 boards plus another ~4x4, so about 112 sq ft. We set up some nice bench work and built a really cool paper mache mountain with tunnels for the trains to go through, but it kind of sat for years with occasional use and view. We added a new building here and there. Now we've gotten back into it and are going to finish out the landscaping with roads and such. I've looked into lighting. There's a real nice and easy plug in system that will probably run about $400. Haven't pulled the trigger yet, my son needs to come back to get his views since this has been a joint project since he was about 12 (16 years ago), but probably will. I think it'll turn a neat setup into one with a real Wow factor.
Not that I really care whether I have an answer, but it is a good answer to "What do you do all day?"
