Cover art for 405 lyrics by Death Cab for Cutie

ben gibbard is a freaking genius, i love the lyrics he writes! im so happy death cab is getting more recognized for their work, the same goes for the postal service. im from seattle, and with death cab being a seattle-band, im proud of them and ive been a fan a long time. this song, 405, is my favorite. im not really sure what this song is exactly about, but i know its about I-405, a highway that goes right into seattle and maybe this song is about memories of him always taking that freeway to get to this girls house or something

I-405 actually detours around Seattle. Ben Gibbard is from to 120 miles north of Seattle. He was driving down to Seattle to the girls parents house and either by purpose or accident took 405 around Seattle missed it.
