Who is G. Windrum?
If you Google that name + Disney you end up with only one factoid: G. Windrum was part of the team that did "If You Had Wings" at WDW. Other than that, I can't seem to scare up any more info on this Disney Imagineer. Don't even know what the "G" stands for.
We can add at least one more factoid to G. Windrum's profile, however: this Imagineer worked on the Haunted Mansion, and made a contribution worthy of a tombstone tribute in the graveyard. You'll have to look awfully hard to find it, however. See MURDNIWG on the far left?
