I just checked in on Thursday after a trip and the process was relatively quick and painless (contrary to some of the stories I've heard from previous years). I think my only complaint would be that the customs officer could maybe use a little more sense of humor. When he asked if I had brought anything back with me, I replied, "Nothing but the dirt under my fingernails." He didn't seem to think that was particularly funny. :-?

You're lucky that you weren't fined for importing foreign soil without a permit.
