It's maintained by the Bayfield Lion's club, but it is public, and there is no oversight. Many people joining the local clubs to use their club ranges often cite experiences with others at the Bayfield range as a motivation for joining the club. I've only visited it once and never shot on it, but it looked decent enough when no one else was on it!
Oops, just found the extended rules...never mind! Looks like Summit doesn't allow working from a holster, and they define 'rapid fire' as more than one shot every 3 seconds. That wouldn't even let me practice a conventional bullseye course of fire, but I guess they get enough yahoos in there who put too many holes in the ceilings and walls.
You're correct no holster work. The range has booths with a small counter at the front negating draw from the
holster, it's easy enough to do your holster work dry at home. As to the 3 second rule, all I can say it's not enforced.
