Elvis Presley Park
Even if you're not an Elvis fan, I think you'll still enjoy a visit to his birthplace - I'm not and I did.
The two room cabin in which Elvis was born has been preserved as near as they can get it to how it was between 1935 and 1938. It looked and felt authentic.
On the same site there is an Elvis museum and gift shop - both of which I preferred to the Graceland versions (but, hey, I'm not a fan). There's also an Elvis chapel - not as mawkish as you might expect - and playing areas and pitches for the local children.
The helpful and knowledgable staff are clearly all fans or else very good actors.
