When I was at KSC, I was fortunate enough to be able to walk beside a crawler as the Atlantis was being transported to the pad
Funny thing, there were several crawlers at Prudhoe Bay while the camp modules were being erected. We estimated that if someone stole one and drove off we could still see him headed down the road the next day. These crawlers weren't as big as the ones at Cape Canaveral, but the modules are only about ten storeys tall, built in Seattle and delivered by barge in summer.
So what was it like??? I bet just one of those steel bars is bigger than you.
