I'm planning to dig holes in the ground without permission during a treasure hunt in the national forest.
Are you trying to hide or bury something out there?
I want to disrupt the competition as much as possible.
I'm not sure I understand your motives, but when you're out in nature, you need to respect your surroundings and not disturb the ecosystem. Stick to the rules of your treasure hunt like everyone else and you could still have fun, regardless of the outcome. You could be excluded from any further activities if you are caught digging holes.
Okay, I don't have time to study maps anyway.
It sounds like you are in some kind of organized competition, but you are also in a nature preserve, so you need to be respectful of the boundaries between the treasure hunt and the protected lands. Just have fun trying to find the treasure within the designated routes, and no matter who wins, you will enjoy being outside and experiencing the thrill of fair competition.
