well.. i cant say i have a definite answer i guess i just like industrial stuff and was looking for original subject matter to paint. when i was a little kid i used to call the pipes at the back of buildings "my friends" (super weird, i know.. i'm a tad schitzo haha) plus I just think they're cool looking. maybe thats due to the fact that i once walked down this alley where there were a bunch of industrial pipes while on shrooms )
