Need more "backyard" style arenas

Just one or two more smaller venues with similar vibes to Street Beefs and Scrapyard, something that gives off local small promotion or even underground vibes. Similar ruleset as Backyard, slightly different look/setting, with maybe a significantly smaller cage. I personally find it perfect for a stable of fictitious created fighters, for those of us who like to create our own fantasy league. Just some basic little makeshift venue set up at a park, a warehouse, parking garage (yes all the cliches lol). Nothing crazy like on top of a volcano or anything lol. Now that i mentioned that, i'm afraid volcano with hazards it will be. lol.
