I'd start a Youtube channel called
Hickok45's Neighbors.
As you might guess, i would have to buy the property adjacent to his. I'd pay experts to design and build a state-of-the-art gun range like none other. It would have DisneyLand-style "Lands" -- Rimfire Land, Revolver Land, Pistol Land, Assault Weapon (or AR) Land, Hunting Land, Sniper Land, Cowboy Land, etc.
Each area would be a place designed for enthusiasts for each style of firearm and shooting, where people with similar shooting interests can shoot for fun, compete and try new toys. There would be a snack bar and a lounge where patrons can enjoy each others' company and talk about whatever.
Basically, it's a gun club, but with more capacity and facilities than any in the country (world?). There would be expert trainers, tactical "rooms", laser tag for the kids and adults, gunsmith classes and services, etc, etc, etc.
The idea is to piggyback on Hickok45's name recognition to attract shooters. Of course, he'd be invited to give lectures, story telling times, instructional classes, and so on.
Use of the place would be free of charge, but there would be a foundation to solicit donations from the public to keep it running perpetually.
There would be armed security -- uniformed guards and plain clothes safety officers -- keeping watch to make sure everyone is safe. If a nut job shows up with bad intentions, I'd want him stopped before his trigger resets for a second shot. All security would be wearing state-of-the-art soft body armor and armed with 9mm's and Tasers -- Tasers for crowded areas. All security would work in teams of 2 or more.
The place would advance the education and training for the public re: 2A rights, firearms and self defense. It would provide an experience like no other place. It would create many, many jobs for people who enjoy shooting and helping others enjoy it, too. It would have its own factories for producing ammo for the range's use and for sale to visitors. There would be pro shops to help shooters pick out firearms and accessories with hands-on demonstrations and "test drives". Small businesses and Vets would be given a place to market and demo their products.
I was serious about the DisneyLand-like model. Secure parking, shuttles to/from your car, lots of staff to help you find what you're interested in, valets to help carry larger gun cases and stuff who can also watch your belongings as you enjoy your time there, giveaways, door prizes, and awards for competitions, ....
If it get's big enough, maybe even a monorail and stage coach to carry visitors between various "Lands."
At some point, I was thinking of making a West World theme park, too, but the technology hasn't quite gotten there.
