The steps in that picture are 18" deep, 4' long, and 7" thick. The catolog of the supplier says they weigh 97 lbs per square foot, 582 lbs.
Give me a couple straps (and a Bobcat), a crow bar, a 30" crow bar, and a couple pieces of wood for under and I can move them around all day. I think granite is even better than Lincoln logs!
