Thanks everyone for the advice. I may have been a little confusing about the SD comment. We live there and every year when we want to book a campground at a park where there are lots of things to do such as Lewis and Clark in Yankton or Palisades they are always booked months in advance. I was wondering if it was the same in Alaska but apparently not. My husband and I keep having the same conversation about how much we need to plan in advance in terms of booking dates, etc. Believe it or not I'm the free spirit.
