Trainspotters

OMG..Did you know that there are real live trainspotters?? What's a trainspotter you ask? Good question, cuz when I heard it I had to ask too..I didn't want to assume that it was self explanatory just by the word, cuz, really now, could it really mean a person who spots trains??
Well, you were right! It sure is a person who spots trains..now you probably think that this is a Brit thing, but no it aint..yes, apparently its a worldwide thing and peeps do it in the US too..go figure..
What a trainspotter does is go to a busy train station in London, Clapham Junction Station I hear is the best and busiest place for this, and write down the ID number of every train that passes thru the station. The goal is to see and document every train that has been made...they write down the train number in a note pad..
Ever since I heard that there are real live trainspotters I have been obsessed with them. I want to find one. I want to talk to one. I want to take a picture of one. I want to interview one. I have tried to look for them but I haven't seen one...who knows, I might find one yet.
To most Brits here that I've spoken to seem to think that trainspotters are a joke and are just losers.. But I'm fascinated by them..I find it amazing that someone can spend all day on a train station platform and write down the ID numbers of every train that passes by... It does seem a little boring...I'm sure there's lots of distractions in a busy train station like Clapham Junction...They could be 'people watching' too..or maybe not.
So, what do ya think??? Should I abandon my quest in search of a trainspotter? Would ya want to read about it if I did find one?
