I got to see this in Pittsburgh last year during the first run of the tour (and ran across the awesome Fraley's Robot Repair shop art installation on the walk from the parking garage to the theater.) It was a great show, full of great facts and audience participation and Q&A and awesome stories (Adam: I've only ever broken one bone. Audience starts to applaud... Adam: "You may clap now, but that bone was my seventh vertebrae. Yeah, I broke my neck.")
The only part I was disappointed in was the finale where they "launched" Buster into the air. After the stunt with the crossbow earlier in the show, where they promised it was the only time they were going to lie to us, the trick with Buster and the barrel of explosives felt like a real let-down.
