From Florida and Only Florida

I'm drinking a tasty cup of orange juice right now, and I'm finishing up the carton.  Looking over at the carton, I noticed a few minutes ago the "From Florida and Only Florida" description.  Why is it that people feel better about oranges from Florida and potatoes from Idaho?  

If there was an orange juice brand that was fresh squeezed Idaho orange juice, I'd buy it!  and why hasn't Tennessee and other states claimed other vegetables or fruits?  Rhode Island could claim radishes.  Washington could claim watermellons.  

I guess Texas has their toast and Mississippi has their mud pie.  But I could go for some Rhode Island radishes and Washington watermellons.  I think it would even be nice if Tennessee claimed something... maybe it would help the state bring in some more revenue from around the nation.  

Tennessee Tomatoes?  Fresh squeezed Tennessee tomato juice - it's the only tomato worth tastin'.  If we advertised this as Idaho does their potatoes and Florida does their oranges, the nation would be convinced that tomatoes from Tennessee are just better.
