You would love my basement! When I last moved 25 years ago, I had to pare down my accumulation of about 180 models, but some were boxed to save for eventual retirement. A couple of years ago I started to open those boxes and am continually amazed by what reappears. Not to mention I have been building and accumulating ongoing... and I too have a half built Roadrunner with a spare set of cores standing by.
