Boon-docking means locations without electricity/water/sewer. So I am confused as to what you are looking for.
Are you looking for camping locations in the deep forest with no facilities or campgrounds with all of the facilities.
I would also suggest that you do some research on the two states and decide what you may be looking for as to geography. Some parts of both states are open plains where the winds blows Texas into Canada during the summer and other parts that are mountains and pine country.
