Well, as a kid of the 1970s, Lionel Playworld was my place.

It bothers me that my kids don't seem interested in action figures like I was when I was their age. They do like video games, but not to a great extent, and my wife and I certainly don't let them "veg out" in front of them for hours every day. They never ask to go to the toy store and if we skirt around the toy section at Wal-Mart, they don't really seem to notice.
I don't know what changed, I guess that's how it goes though.
