禁酒

禁 = 林 + 示 : There's a small forest of two Christmas trees (林) in front of the encampment ((e)n4). Although there's a sign clearly stating that it is forbidden (示) to touch the trees, Joan of Arc (ji) set up her guideon (示) so that it is supported by the two trees and she can practice pull ups.

酒 = 氵 + 酉 : The rooster and Maud Younger are downing some baijiu in the outhouse. Maud Younger doesn't notice though that the rooster is hiding a bottle of water behind him and every time when Maud is not looking he replaces his booze with water.
