From my personal experience, one of the best ways to get younger people interested in safe and responsible gun ownership along with standfast mindset to protect and preserve these ideals of self reliance and gun culture is to get them acquainted with the frontier days of this country's history. The French and Indian War, harrowing tales of Indian raids and how some survived against all odds, the tomahawks, woodcraft, and rifles of the adventurers brave enough to wander into the unknown, the Old West bank robberies and gunfights and how armed good guys flipped the tables on baddies, and everything along these lines.
If I were to purchase that town, I would have it completely turned into a living history lesson for all to come and attend. Full time reenactors will staff every building and carry out day to day living just like in the time period. Other reenactors will stage memorable events from time to time that will be posted and scheduled on a visitors' notice board. A band of mounted Plains warriors might stage an attack on the town one day. War whoops, arrows flying, gunsmoke, townsmen manning the balconies and returning fire. Then a regiment of US Cavalry troopers will stop by to get water and provisions while on hot pursuit of the raiders a few hours later. Celebrities of the day will also pass through from time to time. Teddy Roosevelt, Annie Oakley, Buffalo Bill Cody, other prominent US politicians, presidents, and corporate leaders of the time.
And of course, GUNS. Guns, guns, and a lot more guns. Various situation-themed ranges depicting Old West scenarios behind these buildings. Professional instructors and guides on hand to ensure that everybody will have a blast with every period firearm available along with a history lesson to go with every piece. From 1830s single shot "Dragoon" cavalry pistols right up to the 1911, 92' Winchester, and everything in between. Even an "old" Spanish matchlock arquebus "discovered" by one of the "miners" "living" in the town will be available to shoot, along with a couple of slightly rusty comb morion helmets. Let's see how many kids can resist trying on one of these tinpots while heading down the line to put a few rounds on a cardboard baddie with a Auto-Ordnance 1911. And when that initial excitement is out of their system thanks to the 1911s and C-96 Mausers, they might be interested in the longer demonstrations on how to maintain and shoot a black powder frontstuffer at the other booths.
The potential for that town is limitless. But this is one of those projects that are absolutely "go big or go home".
