Looking Forward to Summer!

Jonathan and I are trying to plan a possible vacation this summer to Kentucky or Tennessee. We'd love to do some hiking while there, so we dug out the backpack Jonathan's sister gave us to try it out with Luke. He loved it! Jonathan "test drove" it around the house and Luke thought it was the greatest thing.
By the way, if anyone has any good tips or must see sights in the area we're looking at, let us know. We're trying to get away with a somewhat cheap vacation that isn't too far away, considering gas is projected to hit $4 a gallon by summer! :(
