Door Prizes

So, Here's the idea:
- Each vendor is asked to donate a small value prize.
- Each patron has an opportunity to sign up for the door prize.
- Every 1/2 hour or so a patron name and a vendor name will be drawn. 
- A public announcement will be made to identify the patron (must be present to win) 
and when they are identified, the vendor is named and their wares are highlighted. 
- Hopefully, fun will be had by all.
    
-Oh, and there's a BLUE LIGHT!!  ;)
