Santuck Flea Market
I agree with Randall - it's a great flea market. It's a bit north of Montgomery on Highway 9, so I would guess your easiest route would be 280 to Montgomery, then head north on Hwy 21 and then take Hwy 9 in Wetumpka (near Tutwiler Prison). From there, it's not hard to find - you'll encounter the traffic, lol.
Have fun!
