There’s a simple rule in extreme sports: look before you leap.

In general, this is much easier said than done. While you can have a general idea of where you’re going, you can never be entirely sure about what hazards will pop up, or what ways nature will decide to mess with you and ruin your whole run.

In some cases, this isn’t so much the fault of “nature” as it is “some dude in a truck.”
