I lived in a small northern ontario town and there was fucking nothing to do so we spent a lot of time exploring the hills/forests. The place is actually a huge meteor impact crater so there's lots of rock formations/hills/caves/whatever.
One major landmark was the 'ice cave' which was, well, an ice cave. You had to descend down a short tunnel hidden from sight by what looked like a pile of rocks that had fallen down a long time ago, and once you got in the whole place was freezing cold with ice on the walls/ground even in the summer. None of us ever went far in there, I think I was the bravest but I quickly turned back when I realized I could smell an animal of some kind. It smelled exactly like the porcupine they kept at Science North (a natural science museum, one of the main tourism places where I'm from). Like really nasty BO, basically. In retrospect why the fuck would I even go into a cave in a place known for having tons of bears?
My main hangout as a kid was a small clearing up in the hills behind a friend's house. You had to cross a small creek and the only way to do so without getting soaked to your chest was to jump across a series of planks and such we'd arranged. If you weighed more than 100 pounds or so you'd probably just go right through them, so it was kind of like a 'kids only past this point' gate. Anyways there wasn't any kind of real path or anything and I don't remember how I found it in the first place, but it was a really cool little spot. A small stream of spring water went through the middle and there were wide flat rocks to sit/lie/eat lunch on. I'd go there with friends or alone, read comics, and work on my Ninja Turtle replica weapons. I had cut down a very small tree (maybe 1.5-2 inches wide) with a hacksaw and used a knife to turn it into a sweet bo staff that was good for helping me climb up there. I once used it to whack a dog upside the head because it had broken its chain and bit me in the leg. Good times. Never found any porn though.
