I mail books to CGC (cause unless it's something stupid expensive I'm too lazy to drive up there and drop it off). I live about 15-20 miles south of Sarasota in a place called Venice.
My package gets picked up in Venice, goes to the Sarasota distribution center, to the Tampa (Ybor city, technically) distribution center, back to the Sarasota distribution center, to a Sarasota Post Office, to delivered to the CGC offices. It's a fun process to watch, especially if I send priority and it all happens within a day.
