How did you discover and get into Touhou?

It's a simple question with many answers, how did you discover and make your way into Touhou? For me, I got into Touhou through some pretty funny way, but not really through memes. Well, to begin, it has to do something with trains, of all things. There are these MAD style videos, called Tetsudo MAD, which in itself is pretty much its own spinoff of MAD itself, basically the YTPMV thing that's all over youtube. These Tetsudo MAD are centered around railway related things, and usually use Japanese music and songs of all kinds, sometimes even non-Japanese music. Around like half of these use Touhou music. One of the more popular instances of these is one of Keikyu railway, using Night of Nights, which was made known to the wider world through 8bitdrummer. Through these MADs, I was pretty much being exposed to Touhou at that point, which led me here.
