There is an annual outdoor sale that starts in Gadsden, AL, right near me, and leads all the way up to Michigan. This year will be my 3rd time to go, and I'm already starting to get excited. If you have the time and money, you can find literally anything you want. I can guarantee you there will be plenty of old fluorescent lighting, street lights, you name it, you will find it. It always starts the first Thursday of August and lasts through the following Sunday. Imagine this long road that leads to small rural towns with nonstop yard sales for over 600 miles.
