I don't know if any one day of the month on average is hotter than any other, but I'd be willing to argue the fact that the second Sunday of every month is the hottest. Sunday was full of humidity and hot hot heat. Even with the weather its pretty cool to see that Second Sunday on Main isn't losing any steam rolling into its 11th season. As a matter of fact, SSoM has expanded a block south to 12th St.
If for some reason you did not make it your next chance is July 10th.
Drag races and water balloons SSoM Pride is always my favorite.
