I haven't "practiced" in decades, but I still apply knowledge to casual summertime fun at the cabin. While I really no longer need to test myself in any way, I do prefer to approach the casual outdoor experience with a touch of old school tactic, which means lighting fires with no accelerants, making do with only what you can carry and without whatever you have forgotten to pack. I just like to demonstrate to the kids how it was once done before the modern novelties came about. I like to show them non-poisonous limbs to mount the 'dogs, various safe plants along with certain dangerous ones, and I like to have the little buggers construct a lean-to in short order. I get my refreshment course through them, heh.
When I did need to rehearse my tactics back in the day, however, I always had access to a piece of crown land that had been leased out for 100 years to our group since 1967. I think it is around 69 acres or so, and is still in relatively the same shape as it was when I first went there. It is effectively an early 20th century logging camp that has been replanted with Lodgepole pines. The many paths and trails make for wonderful spots to enjoy the wild brush. Above all, it is wild, but still close enough to civilization that should the need arise, one could always go for supplies or help.
