If anyone happens to be in the park on March 3 or 4, and there happens to be some wondrous, unannounced merchandise event going on for the 20th anniversary of the Indiana Jones ride... and that person happens to feel so inclined... I would gladly reimburse for any cool limited-edition Indy-related collectibles.
Guessing there won't be squat. But I really like the stuff I have from the 10th anniversary (pocketwatch, snowglobe, perpetual calendar, etc - photos: http://www.colddeadfish.net/dlr/indyevent.html ). Would be great if they did some little thing for it.
Sadly, I cannot make it out in March, either way.
