I'm from Canada, and we drove 17hrs to get there, and it was worth every second! The drive from Nashville to Memphis was boring as hell though, lol.
You definitely have to hit up Sun Studios. I'm an Elvis fan, so a visit to Graceland is always a must. Check out the Gibson factory just off Beale and watch 'em build some archtops. I know everyone always has the best place for ribs, but honestly, some of the best ribs I've ever eaten were at BB King's on Beale. There are some cool shops to check out as well. We tried to go to one of the dives from Diners/Drive In's/Dives, but unfortunately, it was closed.
Next time I'd love to check out Stax as well.
