bus or train
If you can do without the bike a few days, shipping it ahead via Greyhound is much less expensive, and you don't have to be on the bus. But where possible, I take Amtrak and take my bike with me. Some trains have bike racks so that you don't have to disassemble. The ones that require you to box it up have nice large boxes that require very little disassembling. The boxes stay upright on the train and don't get thrown around like they do on planes.
