And I would like to organize a game where everyone could participate and the winner win a prize.
We are 212 participants, which could choose or not to participate.
The prize is a weekend for two in the moutains.
Last year, the game was to build the best snowman.
Before that, the game was to find a specific drink taken in photo in one of many bars in our camp.
I want to do something original and fun but I don't have many ideas.

Can you help me please ?

(Sorry if there are many mistakes, english is not my main language ^^ !)

Thank you, any help would be appreciated !
