LOL, Hhhmmmm, maybe that why he seems so un-concerned of my presence, pretending not to be bothered and then to jump me at the last moment for my bike and run off to father christmas with it!
We have a few walkers and the odd kid in there from time to time. I did contemplate putting up some "KEEP OUT - PRIVATE PROPERTY" sign, but in the end I thought they problem draw more bad attention that actually help anything. The woodland also runs in parallel with a quiet lane (20 mph and practically dead), but there is still a risk of a branch falling on someone or something.
I've looked up R-A-P, I might well go with that just for peace of mind. Still unsure though to what level the tree need risk assessing for the insurance to be valid in the event of a claim.
I did know of kn03.com at the time, seemed a proper dodgy character and sold some very risky chemicals, not surprising he got his collar felt. I never bought anything from him due to the dodgy nature and extreme high prices. I know a few chaps who sell pyrotechnic chemicals online in a responsible manner and quite happily doing business. As usual, if its all done in a responsible way, its all viable!
Yep, theres a lot of widely available stuff out there that potentially could reek havoc. Interestingly, the agriculural chemical you refer to has had a few controls put on it, but you can still get it if you have a responsible use for it...
As attractive as it sounds of having a free supply of kno3, I think I'll stick to buying it...

My wife thinks I'm mad enough as it is with my firework passion let alone asking her, "can you do it in this bottle?"

Anyway, you better get collecting if you want to get the large solid rocket motor off the ground!
