Because people'll make way less fun of you for dressing up like a cowboy if your gun's actually real, there's Camp Sumter: a new 30-acre shooting range (not far from the National Prisoner of War Museum outside Columbus) running monthly competitions that follow the absurd/awesome mandates of the Single Action Shooting Society, which include use of specific vintage types of firearms, ridiculous dress codes, and even Old West names, so Kanye's grandad's already covered there. The goods:
Bustin' Caps: You'll move through a timed course of scenarios that mimic famous historic incidents and movie scenes, blasting at steel targets with your self-provided, (hopefully) cowboyish firearm, including single-action Luger revolvers, pistol-caliber lever-action rifles, and old-timey shotguns that were favored by Teddy Roosevelt, mainly when he couldn't find his big stick.
Nicknames: It's required (no, seriously) that you scheme up a unique badass alias either representing a Hollywood Western character or alluding to an Old West profession/lifestyle, and register it with SASS to ensure no one else uses it, meaning it's too late for already-claimed winners like "Skillet Creek Charlie", "Buck Snaked", "Koyote McNasty", or "Western Guy"...dammit, "Western Guy" is off the table?! And they still expect people to participate? This is crazy.
Costumes: Finally, you're mandated to don an outfit created in tandem with your alias (they've got affiliated shops all over the 'nets), which can be either historically accurate 19C (spurred boots, suede vests), or just something "suggestive of the Old West" -- implying that Air Yeezies with orthopedic footbeds and Prada Blu Blockers are totally kosher.
