I love puzzles, and love the colour Indigo, so I thought that I would combine them both. I especially like the puzzles that require me to convert some letters to numbers, since my daughter can do those too. Best of luck! Here's what you need to do to find out where the cache is:
You will have a 6 digit number. Take the first 3 digits of this number, divide it by 1000 and add it to the North coordinates below. Take the last 3 digits of that same number, divide by 1000 and add it to the West coordinates below.
Add to: N43 14.480, W079 56.800
Congratulations to metalnewton on the FTF!
