That's the official "thing" to look for when you are in WDW. A lime green Mickey head usually means someone else from the DIS, allowing you to strike up a conversation. OR...they could just be someone who really likes lime green
Only 1500 in 8 days? I'm just back and sorting through 2,300 from 5.5 days, lol. Most of those are in RAW (parades and fireworks in JPEG) so I've got a lot of work to do!
DW and I have tried using the Home Depot LGMHs in the past but they either fell apart or fell off, etc. Conveniently, WDW now sells small foam Mickey heads in multiple colors - including lime green - at many of the cash registers for $1.95. We had each bought one in September but the one on my camera bag got pulled off (I think on the bag nets under the chairs on Soarin). So I bought three more this week - one to replace the lost one on my camera bag and two as backups in case one falls off down the road.
I think many DISers have the same idea because I had to go to four different checkout counters to find three total lime green Mickeys. I know they are for sale in EPCOT and the Emporium in the MK, can't remember if I saw them in DHS or AK.
