I have asked this same question on another board months ago. All the Alaskan members who responded seemed too laid back or too screwed up on rec drugs to be able to give me a solid answer. If US Customs is so laid back that they rarely open a package, it seems to be the best place to have your large shipments sent to. Once they are in Alaska you could send them UPS overnight express anywhere in the continetial USA.
If this is truly the way it works up there then I am moving to Alaska to set up a major remailer operation.
