Well I just couldn't pass up exploring this Preserve today. I was so happy to hear CHEEEEEESE BURGER. I also saw a bunch of White Tails. I think they thought I was another deer because who else would come back here. Ok back to how to get final coordinates. At Posted there is a sign on the south side of the kiosk right near parking. There is a map with some parks that are in speaking bubbles. How many are north of 104. Spell your answer and plug that into the checker for final coordinates.
You can validate your puzzle solution with certitude.
Congratulations to TheTilleyHat for a FTF!!!. He too must like preserves.
