Snag.1

Stupidity: Carl buries the case with the money in a field by a fence. He looks at the fence line and wonders how he is going to be able to find the spot when he returns. He plants an orange ice scrapper to mark the spot. The scrapper is only 6-8 inches, but it's the middle of winter in Minnesota. The scrapper will be buried by snow. He should have marked the spot by tying something on the fence. (01:18:26)

Trivia: Casey is playing catch with a football at a Chicago Bears game. Casey throws the football is back underhand like it's a rugby ball and not the American way overhead.
