COLLINSVILLE TRADE DAY: A UNIQUE CULTURAL EXPERIENCE TO THE REGION Written by: Aaron Pendergrass Local Realtor Collinsville Trade Day is definitely a must do for any of the locals and visitors of Northeast Alabama. There is a wide array of merchants from fresh produce, tools, clothing, plants, animals... the possibilities are endless! Trade Day as us locals call it takes place every Saturday from 4:30(sunrise) until about noon(when the vendors pack up). In the early 70's Trade Day began as an open air flea market for Locals to sell their produce, crafts, and other merchandise. (1 comments)
