As well, and this is little known, Pineapples can be brought back to the mainland. They don't have to be the pre-examined ones that cost a small fortune at the airport shops.
You can buy them in Costco for under $5 each, make sure they're clean (and they are), put them in a box and take them home. Don't seal the box in the event Ag. Insp. wants to look at it.
I found this out by going to the Ag station in Kauai and asking what could be taken home. They handed me a sheet of paper that listed just about everything you might want to take home. Unfortunately, I left it behind with the concierge because THEY didn't think pineapples could go to the mainland either
