Dear Cacher,

I have enjoyed solving so many puzzles locally that I thought it was time I tried my hand at setting one, so here is my first attempt.

Once you have figured out the method in this madness to lead you to the final (two should be enough) you should start from here:

03504548 04289636

There is an unactivated TB for the FTF, otherwise it is just the glory of the chase.

Good luck,

Bob.

ps

If you get the right method the final coords should be obvious, but if you need to check your work here is a checker for you.

You can validate your puzzle solution with certitude.

Congratulations to SeeingItDifferent for the FTF
