Letterboxing in Como Park (part 2)

With three fresh stamps in my logbook, I started following directions to my fourth and final box of the day. I saved 10,000 Lakes for last because it had the most cryptic clues. It took me into parts of the park that I had never seen before. First stop was the monument above. It was conveniently located next to a restroom building, which became my second stop.

I blew my nose on some two-ply, then back to the trail. I had to duck under an intimidating barricade to access the next location. The hole in this table is beautiful in an urban-decay kind of way. It's complemented by some charming graffiti.

This structure near the park bench looks like something you might find playing Oblivion, deep in an imaginary forest, although the chain link fence gives it away. This eroded architecture looks like it must have been part of a larger building at some point. I would like to find out more about it. Does anyone know its history?

Finding this letterbox was a fun little journey, but the best surprise was what I discovered next. Tucked inside the box was a tiny "hitch hiker." These mini-letterboxes are designed to travel from one box to another, carried to new locations whenever they're discovered. I stuck this one in my pocket to drop off when I go letterboxing again. I wonder where it will end up next?
