I had an Uncle that lived in a surburb of Atlanta when I was a kid that had a huge Lionel layout in his basement.
His son was a good 10+ years older than me so I never really got to know him too well.
I do remember him having a brand new 68 Camaro, maybe an SS or RS.
Anyway, back to the basement.
That's where I'd head whenever we'd visit. He didn't have scenery or anything, but a lot of cars and two or three engines that used the tablets to make smoke.
Had the big double handled controller with the whistle switch on top.
His layout took up a whole corner of the basement (maybe 10X20? That was a long time ago) and the basement was huge!
