It's the ski area in Minnesota that is actually on a mountain. They have 23 runs and a separate snow board park. You will hurt yourself, laughing. People downhill ski here, some even love it, but get out your topographical map of Minnesota and you will see what I mean. Cross Country Skiing is very similar in equipment to down hill skiing but the activity takes place on a much more level surface, most of the time.
Any frozen lake is a great cross country ski path.
All locations rent equipment. A yearly festival of all things winter. Ice Sculptures, parades, music, and a giant snow slide are just some of the highlights. Make sure you buy a Winter Carnival button to show your support. You probably won't have much of a choice, if someone notices that you do not have one proudly displayed on you winter jacket, they will most likely offer to sell you one.
