As we did with our indoor gallery from the show’s hallways, we’ve gathered up the most interesting sights of World of Concrete’s outdoor demo lots in the gallery above. Each year the show gives attendees the ability to give all kinds of tools, trucks and machines some hands-on attention. This year, John Deere and Western Star took over huge swaths of the Gold Lot with operator challenge spaces. And of course there were lots of opportunities to operate a trowel.
