Since we work here at MPA with a large number of running and multisport events, we are discussing frequently the pros and cons of inflatable arches vs. metal truss and scaffold systems. Each system has its merits, but the one thing we always point to as an advantage to inflatables is the quick up and down and the small crew required to execute. Nothing is easier, quicker, or more cost effective to transport, store, maintain and modify with new signage.
