Why do we do this?

[BNSF_or_SOO]

Haahaa. Funny subject eh? Lately when I have been trackside, whether it be alone or with a friend, I wonder.....why do I do this? I enjoy taking pictures so much. I enjoy being trackside so much. It lets me forget about everything. Ill stay out in the cold for hours just for that one shot. For example, this past weekend at Chicago Ridge I waited for an hour and ten minutes on the Southwest Highway overpass, for a westbound IHB movement. The normal human would not be able to feel their body, yet alone their hands, after this amount of time; yet I duked it out and got my shot. Every weekend I plan where I am going to go.....Joliet, Bue Island, Homewood, Deval, Bensenville, ect., ect. It is all I look forward to each and every week. I cant wait to get a car so I can drive to Iowa, Texas, and the Powder River Basin. Its all I want. My friends always ask me; what is wrong with you? HAHAHAAHAA. I dont think Im that messed up to get a response like that but still, I cant figure out why I do this.

Has anyone else felt this way or help me find out why I do this.
P.S. Sorry for the long rant.
