shipping fenders?
I've never used Greyhound for shipping anything, but can recommend this guy:
Tyler Sheff
FairPricedShipping.com
888-762-7158 (Ext. 701)
He or his wife Jill will respond to the "Contact Us" tab on the website but you'll get a quicker quote if you just call the toll-free number.
Great prices, wonderful customer service, they prepare all the paperwork, and it's quick too. You just need to have a loading dock / terminal (like a lumber yard) at both ends of the shipment.
