To be fair, in this anti-social day and age, you may not need teamwork to get this cache, but it might help, if for no other reason, commiseration and collaboration.
You could also just bring a full arsenal of TOTTs and plan on staying a while.
Either way, cache is easy to find but difficult to retrieve. I'd suggest string, or toothpicks as TOTT of choice, but you could also bring duct tape, or a ball point pen, or a gallon of water, or a fishing pole, or flashlight, or crochet hook, or bandaids, or wire, or Leatherman's tool, or a granola bar, although I'm not sure which will help you.
I'd suggest most strongly, though, that you bring a geobuddy.
Laughing at our mistakes can lengthen our own life.
Laughing at someone else's can shorten it.
