Tracy and I did a ski trip in the Great Sand Dunes National Park in Colorado last week on our way to our sister Christie's graduation from medical school at Creighton. We've always wanted to try it out and ski them from one side to the other to see how similar sand skiing was to snow skiing and if it was a possibility to train on them during the summer after the snow melted. We finally skied them last week. The skiing turned out to be great on the sand too. The sand dunes are only about 8 miles across the longest point, but the dunes rise from 8,175 to 8,925ft at the highest point (tallest dune is 750ft) so it was a good workout to get across all those hills/dunes and back. It is definitely an option for us for training when all the snow melts in the mountains and were aren't headed to europe to ski in a tunnel. Check out the pictures in the picture gallery of the trip.
