l love to climb buildings, trees and basiclly anything l find in my neighboorhood. is this a sport????????????

Simple answer is yes, it is a sport, maybe not as visible or well known as parkour but the same venue & idea of taking whatever is there & doing something with it. What you're doing is climbing & the techniques used based on the skills most climbers have.

Bouldering is another sub-sport where the idea is to focus on easy to find routes that r short, hard problems. l am pretty sure you'd like it, all it takes r shoes & a chalk bag so it is pretty cheap.

Most people that boulder have a local spot near where they live that does not require a crash pad. Since you're creative my guess is that you've seen some rocks worthy of working on in ur travels.

What this will do for u is give u more variety in technique, build ur strength (use slopers until ur hands r strong then crimping is OK). This will expand ur creative horizon & what you're willing to take on.

Have a blast.
