Couple years back we were deciding what to do for my wife for her birthday. We decided on a road trip around to some fun spots in the state we had heard of but not had the chance to check out or really explore. Decided to pick a quarter of the state & find a few fun things we had not checked out before. With the help of the internet, tips from friends & a really cool book ( Oddball Colorado: A Guide To Some Really Strange Places - is a series you should check out and see if they have one for your state) we came up with a few places to hit along with anything interesting we could find along the way. One of the places we checked out was the Great Sand Dunes National Park (near Alamosa, in the San Luis Valley)
