Hi this geocache is very complicated!!! You have to crack a safe with a 4 digit code. Once open, you will find the final cordinets!!! The other locations along the way are the 4 numbers that you will need. The first location is more help and instructions. If you need help, don't hesitate to ask. You will also need water for one of the stages. You will know what I mean!!!
If you are better at math, then coordinate finding, you can find the code to the safe by answering the four math problems in the hint. I personally think going to the locations to solve the puzzles is a whole lot easier.
