Well, I'm getting ever closer to 500. ^_^
As for Inuyasha/Sango, well, other than the one mentioned by Fatuous One, can't think of any off the top of my head. Which is unfortunate since this would be my third favorite alternate pairing in series behind Kagome/Sesshoumaru (even though they are TONS of the cliched "OH NOES! Inu iz wit that biotch Kikyo!!!!!111111 Im runing aw4y! ZOMG! I ran into S3SSY! HOTZ SECKS 2NITE!" fics, it's still my favorite alt), and of course, Inuyasha/Kikyo.
