I drove through Montreal last year on an afternoon jaunt up from Plattsburgh, NY. Next time I will plan better.
I had no map, no Canadian $, no cell service, and no French-reading abilities. Pretty much drove up, admired the views, walked around, and after a while somehow managed to find the correct highway back to NY. It's a beautiful city OKCat. Geographically it's laid out similar to Jacksonville, with a peninsula-like main downtown area, surrounded by very high-clearance bridges. That's where the comparos stop though.
