Mommy Swapmeet

Hello local moms!! I’ve had this idea for awhile but I have no clue as to how well it would be received or how to go about it. So in in this Arizona buy nothing/trading group and I was always so frustrated with the way it worked and how I could never seem to find a person to trade with close enough to me(husband has the car during the day) so I had the idea of starting up a local mom/family centered swap meet. Like finding a large area to accommodate lots of tables or carts where moms could just go around trading or selling the things they were trying to unload lol. I feel like it would eliminate the frustration of waiting for responses back n forth and the annoyance of wanting to trade with someone too far to travel to. Any thoughts? Ideas? I’d love to hear any feedback!
