Hi all - I have been scouring various sources - campendium and freecampsites.net - for free (or <$20/night) places to stay along HWY 2 in North Dakota and Montana during summer. I am solo female so while I prefer private, I also want to avoid dodgy areas. Do you have any suggestions for places where you've actually stayed and would recommend? This is my first go at a request like this, so hope I am doing it right. Thanks!
