You know, I do have my fleece elvin-cloak I would loan out to whoever needs it!
While my dad and everyone were practicing walking down and timing it to the music... he said "I hope my Gandalf Costume is done in time".... I laughed, and he said "Oh maybe you weren't supposed to know about that"
LOL!! Be sure to say "It's wonderful to see you,Gandalf!" when he walks up to you!!!
