Central Park Square is a nice area featuring many "Historical sites", PLEASE enjoy what this has to offer. The cache is not located at the posted coordinates, to find the coordinates you will need to read the "information" here and then go to the second stage.
The Coordinates for the final are: N 40 52.ABC W 098 00.0YZ
STAGE 2 is at N 40 52.094 W 098 00.090
To solve N coordinates ABC: Number of years from when first built in Orville City to when the current one was completed in Aurora multiply by 5 then add 4= ABC
To solve Stage 2: Find the date under "Aurora Cornet Band" and subtract 1807=YZ
