Interesting article, I enjoyed it. He did give 3 clues: "Isaacson realizes others may also head to the park to search, and he welcomes them but suggested, with a wink, “Anybody looking for gold there needs to keep three things in mind… Number One: Obey all park rules. B: Keep safety in mind; there are a lots of thorny bushes and stuff, and snakes in the summer. And on the third hand, it’s worthwhile to give careful consideration to the date of this publication.” Publication date: April 1st, 2019....and No pics of the gold
Good Luck, Ron
