Congrats to Mugger on the FTF!
Thanks for checking my math!
This is a quick and easy stroll and grab.
Nothing mean or devious!

JOE WHITE PARK
Joe White Park, 500 S. Palisade Drive. The two acres at Joe White Park include a playground, basketball court, gazebo, small barbecue picnic areas, many trees and an enjoyable place for a lunch break or an afternoon with the kids.
This is a beautiful hidden gem. Park near the main sign (at the posted coordinates). At that sign you will find the first plaque. Walk the sidewalk that meanders through the park in a counter-clockwise direction. Enjoy the plaques along the way and collect the information to solve the puzzle (the last one will have you strolling on the grass just past the picnic benches - on which you can do your math!). The plaques you need will be in sequential order. The whole adventure should only take you about 5 or 10 minutes. And you might find a new favorite picnic spot!
