How would you plan to do it? Buy, rent, friends place, or just move to a hidden place where no-one can see you?
In Sweden/Scandinavia, they have this law called "Allemansrätten", meaning you can camp in many places for 3 days, then you go to another place (you have to be a certain amount of meters from nearest house etc), and restrictions in some national parcs concerning fire etc, but still a real nice rule that I take for granted, so when I am in other countries, free-camping is not allowed.
But you have loads of space in US.
I have big respect for moose, they can be grumpy and aggressive, especially near city, where they are stressed and their habitat is shrinking, I had a scary encounter in the middle of the night with an angry moose outside Stockholm, something I really would like to avoid.
We don't really have many bears here in europe, but how do you deal with them in the US/Canada, and how to secure the food? Or maybe it's not really a problem, or...? Bears hate surprises, so when walking in remote nepali mountains the locals sing and shout.
