I am about an 11mi rt from work, I just bike the whole way every day, rain or shine, unless I have a school-pickup obligation or something (I've got three boys, I can't fit them all on my bike!). I loathe buses so much, I would never consider taking a bus or figuring out how to get a bike onto a bus rack. I have brought my bike on trains a couple times though, and if I had a commute that was too long to ride the whole way, but I could do some on train, then I would definitely be up for that.
