I pass this spot all of the time and have always been intrigued by it. In its heyday, It looks like it was an old service station that could have been on Route 66. I can just imagine a few old men rocking and cracking jokes on the front porch.
Cache is outside, there is no need to enter the building. You are looking for a nano container. Hope you enjoy this little spot.
Congrats to Diefenbaker on FTF!
