'Twas a jest, of course - and if you were, you're not likely to tell here! I did meet a couple of guys in Lairig Leacach one winter who said they were on the run from the CSA! It'd be interesting to hear how you get on - I'd be quite envious in a way.
I'd be interested to know, too, if ALL woods are owned. There are several areas of land I know of which are ownerless, but these are commons, with minimal tree cover.
I wonder if it might be worth speaking to the FC directly? Just thinking, too, ofanother idea. Whereabouts are you looking to do this - assuming it's not hypothetical? If in SW, I may be able to help. Would you be prepared to work in the woods for an owner - or work on their farm? I don't suppose they'd expect too much!
