A nonstop show for some-odd 45 mins
that would be uber pricey. I have to say I enjoy the sound of the shells in the mountains; a 6" burst sounds like no other in the mountains.
We used to have a kickass show in Tampa. IIRC they spent like $750,000 on shells in one of the shows and had 4 barges loaded to capacity in the bay. It was an insane barrage of salutes/reports and nice bursts. I wish we could pull something a tenth as awesome off, but with just me and one other guy setting it up it'd take days.
