Catweezle 2, our geocaching friends from Holland, introduced us to a really cool puzzle cache they encountered in Holland: see GC1GRTN. We had fun solving it, and since we hadn't seen anything like it in the Corvallis area, we emailed the cache owners (Setzies) and asked for permission to duplicate the puzzle; they graciously agreed to our request!
So, if you're ready for a challenge, grab your BIC pen and start solving the CODE, and then go seek the cache CONTAINER! This is a 2-part puzzle. If you find that you need a nudge, don't hesitate to contact us. The first part involves some basic math, so a calculator might come in handy.
You are looking for a camo'ed film canister, so remember to bring you own writing utensil! FTF prize is a $1 coin.
For part 1 of the puzzle, you need to determine the values for the underlined A, B, C, D, E and F, using the information shown in the image below:
For part 2 of the puzzle, you need to solve the following Sudoku puzzle; use the values for A, B, C, D, E and F from part 1, to initialize the Sudoku puzzle. 
Once you've solved the Sudoku puzzle, plug the values from the colored squares into the template shown below the puzzle.
Because the cache is located adjacent to a busy road, I have marked this as not being kid-friendly. If you do decide to bring your kids (or your pets), please be extremely careful!
