REGISTRATION OPENS 10/3/2022: 2023 Fastest Trowel On The Block And Skills Challenge Words: Dan KamysRegistration for contestants and judges will open on October 3rd, 2022 and run until November 4th, 2022 for the 2023 MASONRY MADNESS® Day Competitions. This year, the space for competitors is limited. Given the interest we have seen on our social media channels, particularly for the Fastest Trowel On The Block, we imagine that the spots will be taken at a record pace. We are looking forward to hosting our 2023 MCAA's Fastest Trowel On The Block and Masonry Apprentice Skills Challenge on Wednesday, January 18th, 2023 during the World of Concrete in Las Vegas. It should be another year of thrilling competition for the masonry industry.Â
