My son and a friend of his are planning a visit to Memphis for several days in April during their spring break. He's planning to take a tour of Sun Records, maybe visit the Mississippi River Museum or take a Ride on a River boat, and spend time on Beale St, taking in the atmosphere. He's also in search of that famous Memphis barbecue. He asked if I could consult the group mind here for some suggestions of places to eat or to visit. Any suggestions will be greatly appreciated.
