I would not recommend greyhound for your hood. I rode greyhound a few years ago and at one of the bus stations I sat and watched greyhound employees grabbing car parts from the storage compartment yanking them out and tossing them on to the concrete where other employees would grab them run over and toss them into the storage compartment of another bus. These guys look like they hate their job. If they hate their job they hate your hood. How many times will it be removed from one bus and tossed into another before it gets to you? And does it go on the top of the pile or on the bottom? It would be OK crated but if the seller won't crate it find another way.
It might be a pain in the neck to arrange safer transport, but it would be well worth it in the end. The weather is getting nice and people are starting to travel, you could find someone willing to haul your hood at least part of the way. My brother was just up here in Iowa from Oklahoma City. I know he would have hauled it for free.
