A thought occurred to me, as I was taking a ride back home from school and noticing all of the opportunities to make my way easily over significantly high walls. This thought was "The only way up is always a pipe." I think this is a little overlooked and should be considered a more streamlined skill in parkour, especially if you live in my hometown with mostly parking lots and two story featureless buildings.
I haven't found any info, after giving it an hour or so of searching, on climbing pipes that are attached to high walls. There are several kinds of pipes that I am talking about:
1. Pipes the width of a baseball, typically leading from an upper story into the ground, following the wall, of course.
2. Thin pipes, the diameter of a quarter, probably electrical wiring, leading from anywhere to the roof (usually, it depends), following the wall. May not be as strong as the above mentioned, but it's still strong and solid with the wall.
3. Loose pipes and polls: Usually gutters (not safe, yeah), or light fixture polls that happen to be following the wall.
NOTE: All of these are so close to the wall that a finger's grip is all you could get behind them.
There may be more, but I simple can't get passed the fact that in my town, which is mostly a parking lot (suburban, lots of empty space, inhabited by featureless buildings), the most useful technique is climbing these pipes. So, does anybody have a link or suggestion regarding training for climbing these things that doesn't involve trespassing or risky guessing games about stability? It would be greatly appreciated.
What about skills beyond just climbing them? What about jumping from cats onto pipes, or vaults to pipes? Right away you can say that climbing a pipe is as intuitive as landing a jump or lifting yourself over a wall, but after some thought, I began to consider all of the possible ways onto these 'vertical bridges' (named because I notice that they are usually A. the only way to the top, and B. easy to get to from either end) from spider walks, to cat hangs, to an existing pipe you are already on. Furthermore, what about the ways off of these? With no good foothold on thin pipes, you must incorperate some skill to jump left or right to reach a balcony or roof. Maybe precisions from pipes. It's a shame that there isn't more information and tutorials respecting how useful these pathways are.
