It's been over 30 years since I've been there, surely things ave changed with matches moving to Atterbury. That said the CMP events should be well attended along with whatever else is run there.
Commercial row used to quiet down during the shooting, in general. Maybe there's less activity now but afternoon and evenings were the busy times.
I concur with costs of everything escalating I can see where there would be fewer people attending, except maybe military shooters. For them it's a military match, but has that declined over the years also?
