Agreed Allen but being involved in car shows for awhile it is building year over year. The planning for something like this might take over a year or better to get the logistics all set up. Getting set up with a club or range that already host these types of activities is almost must. Steel targets alone will cost a "fewish" thousand dollars if the NFOA or a group of individuals would try to start this. Then you get into a facility to handle such a thing. You need a lot of land or a bunch or good neighbors.
First step would be a committee to get a scope and some type of business plan I think.
You might be surprised, I think. For example, the Oklahoma Run and Gun match had (according to their stage descriptions) only the following targets for the entire match:
3 5" plates
4 paper plates
1 falling target
3 full-size torso targets
7 8" plates
4 12"x20" steel
dog target
head-sized plate
That's only 20 steel targets and some paper plates.
...I personally own rifle-rated steel (can take hits up to .308) and can buy paper plates
sufficient to give targets of similar difficulty level other than 1: I don't have a dog target, and 2) I don't have a falling target.
....but I'm pretty sure I could manage a falling target (or borrow one) and I could find something interesting instead of a dog target to shoot. I'm betting John Wallace could say something similar, in terms of having targets sufficient for this. Heartland or ENGC already has WAY more in terms of equipment than this, and can be talked into letting you use them under many circumstances if you are at their range.
I've designed, built, staffed, and run the Zombie Match at ENGC for the last five years or so--while taking a year to set it up is handy, it can actually be done in less than that, including advertising and such. Given Practiscore these days, registration (even payment!), scoring, and reporting scores is a breeze.
The main problems you are going to have (in my opinion) are two things.
Problem 1: Staff. Getting people who know how to actually run shooters in an action setting (which this is) is very different from being an NRA RSO or running a precision rifle match. Not arguing about whether harder or easier, just saying it is DIFFERENT. Finding sufficient staff to make this work isn't easy. Certainly possible, but not easy. People who are good shooters or know rifles---isn't enough. Knowing how to run shooters in safety, how to run a stage and keep it moving and efficient, deal with problems--that's the kind of staff you need for this. The typical NRA RSO simply doesn't work with that kind of stuff.
Biggest problem: Range space.
Something like this either needs someone who owns a couple of square miles out in western Nebraska, or taking over the entire ENGC or Heartland range for a day.
...and it still wouldn't be easy at ENGC or Heartland, simply because the bays are too close together, and too easy to access. Certainly could be done there, but there would be a lot of "go run down this road around the loop and come back to the bay right next to this one" situations unless people get REALLY creative (which is possible).
...now you've got me thinking of how I would run this match at Heartland or ENGC.
Anyway---I think a match like this would be a TON of fun. I think that if you get someone who has run large matches before (preferably action ones), you'd be surprised and what it would take to make it work...
....IF you can get enough staff to run it, and a range space sufficient for it. (If you can get range space, I'm pretty sure we can collectively make the rest of it work.)
