I live in Flea Market central. We have flea marets allll over and tons of garage sales. Also there's a farmer's market not too far off that has one store that sells crazy old stuff in it. Last time I got like Garbage Pail Kids pin, Eureeka's Castle stickers, and some 20+ year old packs of He-Man gum. I went with my now ex-bf, I wish I could go back, but I have no sense of direction and get lost like you can not believe.
There's also a cool farmer's market by the mall here Fri-Sun and you can get yummy old fashioned treats and stuff.
