I'm a 12" AT GI Joe enthusiast from the late 60's to early 70's and had just about every vehicle, playset, outfit, etc. back then. I really didn't play with them that much, but would set them up and let my imagination run wild.
Getting into my teens, I sold everything to my cousin for $50. I was happy with that at the time, but hindsight... anyways, I saw a GI Joe collection on CL a couple of months ago and just had to go check it out. I felt like that kid once again. "I had one of those, I had that, oh, I had two of these". The guy said, "Well, you gonna buy anything or just talk about it?" LOL
I picked up quite a bit that day...pretty much everything AT-related he had and thought I had enough to satisfy my childhood memories.
Two months later, I guess I was wrong!
