ME, MY G/F AND MY BROTHER ARE GOING ON A ROAD TRIP ON THE 23 OF JULY WITH NO SET DESTINATION TO LSAT TILL THE 29TH ABOUT 7DAYS IM LOOKING FOR SOME IDEAS OF PLACES TO GO ATTRACTIONS TO SEE GHOSTTOWNS,PARKS,CAVES,MINES,LAKES,RIVERS FUN THINGS YOU ONLY LIVE ONCE SO ANY FEED BACK IS WELCOME..ALSO TIPS,PLACES TO STAY ARE ALSO NEEDED..I JUST FOUND THIS SITE AND I NOW ITS KINDA LATE BUT ANYTHING YOU HAVE IS GREATLY APPRECIATED.

Missouri has a lot of caves, lakes, parks and rivers! Not sure about ghost towns and mines, but 4 out of 6 ain't bad!
I'm sure there's some quarries though -- they're kind of like mines! If you go, keep in mind Missouri is warm and humid in the summer, so that'd have to be OK with you and your mates.
