Cache is not at the posted coordinates. You must complete the Historic Ancaster Adventure Lab in order to get the information to find this bonus cache. Cache is a gold bison tube that has only a logbook. Please bring your own writing instrument to sign the logbook, and replace as found.
I have waypointed the 5 spots that you will have to visit for the Adventure Lab, as well as some free parking locations.
The final can be found at: 43 13.ABC, -079 58.DEF
The adventure lab can be found here: https://labs.geocaching.com/goto/1379
Congratulations to BWJM on the FTF!
