Looking for something to do over the holiday weekend? Ritter is a great destination for your holiday guests and it doesn’t cost a dime. Enjoy the 200-gallon saltwater fish tank, stocked and maintained by Salty Critter aquarium experts. Head upstairs to check out the interesting green roof. Stop by the children’s department where kids will find a fun make-and-take craft, while supplies last. Then take home a movie or two!
