Opp, Alabama

Mike was passed by a semi today from Opp, Alabama, while we were on the phone together.  He wondered out loud whether this was the name of a town or if part of the paint had rubbed off from the town's name....So I googled it.  It's the real name of a town.  I wonder if the town founders were unable to spell Opportunity, or if it stands for something.  Old Pea Pickers?  I'll have to research more.
