On May 28th, 2016, it took us about an HOUR to cross the Ambassador Bridge, which is about the longest i've ever waited in the many years i've crossed, to get to Windsor from Detroit.
I decided after our wait that we needed a break, even if for only a moment, to stretch our legs here.
I then got to thinking... that this wasn't the first time i've stopped to take a break here after crossing.... and many times wondered why there wasn't a cache here.
Now there is 
At least it's something to get, along with whatever else you may get here, including a break, on your travels into Canada from Detroit.
Enjoy!
