Here is the orienteering requirement for First Class rank:
“Using a map and compass, complete an orienteering course that covers at least one mile and requires measuring the height and/or width of designated items (tree, tower, canyon, ditch, etc.).”
Shawnee Mission Park has a permanent orienteering course that includes an “easy” 1.1 mile course. However, I strongly recommend purchasing the $4 map for every boy participating because this map has special topographical clues required to complete the course. For example, you will need to see that there is a marker on the north boundary between the trees and the field. Because the markers are only 4 inches by 4 inches, it takes time to find them. Overall, it was a good experience to take my troop there. There are also professional meets held by ptoc.org, costing about 10$ to enter.
Enter on the east side of the park; the first marker is on the NW corner of the office building.

Comment from Richard Neuburger, president of PTOC:
“Users of the TRIM course at Shawnee Mission Park make up their own course. There are 71 permanent markers set throughout the park. You may visit them in any order. Leaders could specify which markers to visit, hide the control codes on the clue sheet, and require the scouts to record the control code that they find when they arrive at the control location.
The TRIM course at Ernie Miller Park only has 7 or 8 controls. I don’t necessarily recommend it for the Scouts. “
