The Great Sands Dunes National Park and Preserve located out in the middle of nowhere, Mosca, Colorado was awesome. Wednesday evening was cloudy overcast with thunderstorms headed our way. I started to walk out towards the dunes (which are 3/10 of a mile from the parking lot) But the sound of thunder and the flashes of lightning convinced me to wait til morning. Thursday morning brought clear skies and a lot more water in Medano Creek. Not wanting to over do myself I only walked to the top of the first dune. The sand was actually firmer than I expected. There were kids out there with boogie boards riding down the dunes. Looked like fun.
