Abbe is probably right about a couple of things. First, if you rent the ground (even for a nominal fee) then the person you rent off should not be liable if you put up your Yurt. Secondly, if you think it may be an issue, don't tell anyone. it's a bit like the laws of access in Ireland. If you just go and walk anywhere you like in Ireland, generally, no-one will say a word to you unless you break something. But, if you ask permission, you will almost certainly be told "No", as the land owner then becomes liable if you injure yourself, as he gave permission. I would seriously think about the social experiment route. There are numerous examples of people going and living in, for example, an Iron age Round House for a year. Simply make a video diary of your daily routine, and keep notes. Go speak to someone at your local University and tell them what you propose (Don't tell them your location yet though) and see what they say.
