If you don't have plans for the weekend, ML recommends a couple of fun options.
On Saturday night, head down to Tom Lee Park for Memphis In May's Sunset Symphony. The Four Tops will join the Memphis Symphony Orchestra for an evening of fun on the river. There is also an air show before the music kicks off and fireworks usually follow the symphony. Gates open at 2pm. Remember that you can bring your own food and drink to this event, so be sure to load up the cooler with your favorite beverages and snacks.
If you didn't get enough of Downtown Memphis on Saturday, then you should stick around and go the Redbirds game on Sunday evening. Gametime is 6:05 with a special fireworks celebration after the game. If you don't want to pay ballpark prices for beer, stop by Bigfoot Lodge for $2 34oz Coors Light draught beer before the game. This special runs all day on Sunday.
