Trip To Amusement Park

Truly a gift that will make them scream, and if it doesn't the corkscrew roller coaster will. Buy tickets for the two of you online and print them out at home. At the birthday celebration you can put the tickets in a card and figure out a time when you can make the trip. They'll remember the experience forever, which is much more valuable than any doodad, whosie-whatsit or thingamajig.
