We are looking for city campgrounds or other inexpensive campgrounds near St. Cloud, Mn. We are leaving on a Friday night driving to Duluth (Hwy 23) but would only like to go as far as St. Cloud, MN or so on Friday night. All we need is an electrical hook-up for AC. We don't need any other amenities since we will just be staying overnight and leaving in the morning. We would prefer clean, safe locations. Thank you!
