This was pretty much the same as every other challenging events gig. I mounted 4 horns on the truss, had some horns covering the transition area and the area that people collected there medals and food. I had the horns on the truss on a separate feed to the ones covering transition so I could have different volume levels.
This happened to be the first gig after I passed my driving test too (Passed it the day before the event!) so it was pretty nice to drive myself to a gig for the first time!
