Thanks for all of your replies.
The reason I ask is that every year my wife and I do a different costume and it's always a lot of fun. However, this Spring we are most likely selling our current home and moving - maybe about an hour/hour and a half away...........and I loved my costume this past Halloween (The Incredible Two Headed Transplant - what fun!) and I'd like to do it again, but part of me feels lazy 'repeating' the costume.
I guess if they're new neighbors, it's a new costume, right?
