After visiting the plantation, we drove to Walmart (even away from home, we just can't seem to get away from Walmart) to pick up a supply of macadamia nuts and a few last minute items. Then we returned the car and went to the airport. We discovered that the west US is very picky about what they let in. We suffered through two agricultural searches in addition to the usual security check. No problems however, just the one incident where Ryan's belt buckle set off the metal detector.
