Thirty years of composing clues
Hard to believe it's so
Is it time to call it quits
Which way will I choose to go.
Pepsi has been so good to us
Going to be there when you know
I envision houses standing
Lined up all in a row.
Explanation: "time" is for my virtual clock which becomes a key reference
"Pepsi" and "going to be there" hints at the Pepsi bottle placed near the hiding spot.
"Houses standing nearby", are the bird houses in a number of fields as you approach the hiding area, which as you go from field to field appear "lined up in a row".
A multiplicity of colors
Punctuate the scene
Your virtual numeric devices
It applies when you know what I mean.
It's part curiosities and oddities
There's an implicit faith in my nature
An outlook born in research
A study in my nomenclature.
Explanation: "multiplicity of colors" is an area overview, with green, brown, red (in the nature signs), and lake and various tree trunk colors. There are also multiple places to enter the Park or get to it.
"Curiosities and oddities" point to the huge tree trunk in the turnaround area with no limbs or leaves, and the park bench that faces into the woods rather than the open park space.
"Nature" is a veiled reference to the open outdoors. "Research" and "study" instruct the hunter that this may require additional homework and examination. "Nomenclature" tells hunters that I use a different language- that of double and hidden meanings.
Some things stare you in the face
Leading you here or there
But I found it said nothing
Alone in a world without care
In life you find you have to figure it out
But at times we need instruction
Sources that are there to help us
Think and aid in deduction
Explanation: "stare you in the face" relates to the round silver-dollar sized market on the tree closest to the spot; the brown directional sign pointing toward the location; and another reference to a clock "face". (I also worded it that way in case the temporary closing of Route 98 on the west side lasted longer than planned. It was only closed two days. There was another way to go "Leading you here or there".) That clue also referred to all the geographical markers with arrows indicating direction; the fork in the trail near the hiding spot and again the number of ways to enter the park. The last two lines in the first verse relate to the marker with no further coordinates or instruction. The whole second verse is a discussion of those same directional signs used in the GPS brown markers all over the park.
If you look you'll find combinations
A centerpiece of this year
Time after time it will be there
Look down its pretty clear
When you get it I'll hand it to you
From there you may find direction
Think of an aspiring flyer
Who fails on final selection
Explanation: "find combinations, a centerpiece of this year." Route 98, the only direct way to get to the location, when combined adds up to 17, as in 2017. Two trails near the hiding place "combine". "Time after time" refers to a clock face again, and "looking down its pretty clear" helps visualize the clock face from above. "Hand" is for clock hands. "Find direction" are the GPS markers. "Aspiring flyer who misses out on final selection" is a metaphor for "wash out" which is the very obvious erosion on the one direct path from the circular turnaround.
Like an aging sentinel
A beacon along the way
Others reach out in welcome
While he stands alone from the fray.
A face full of shadows
Nowhere left to turn
Guidance to a new beginning
And a view of little to discern
Explanation: "aging sentinel" is the large, tree trunk with no branches. It is very obvious when you look at the grassy area in the circular drive. "Others reach out" are the trees behind it. "Stand alone" again describes the tree trunk. "Face full of shadows" tells you "Five O'clock" which is the virtual location of the entry path if looking down on the turnaround as a simulated clock face. "Nowhere left to turn" is the end of the road into the park. "Guidance" leads to the path. "Little to discern" is the bench looking into the woods. There is plenty of open space behind it, but it faces close to the woods.
