to me it depends how your moving them.
one or 2 at a time on your bike or walking – no ones gonna bother you.
if you rock up with a trailer and the car and start carting away loads – dont be surprised if you get a visit from the cops when a nosey reports you – afterall they belong to someone – and a certain % of logs are left behind due to them providing a valuable habitat in the ecosystem.
You could contact the land owner and ask his opinion. – once you have his good grace its not an issue how you move em is it.
