Nova Scotia
I flew into Halifax and used it as my base of operations for exploring the province. Driving around was quite easy. The only problem I had was hitting the Angus L. Macdonald Bridge at rush hour going from the airport to where I was staying. Traffic went from half a dozen lanes to one. And I was caught in the middle of traffic when I realized that there was a toll. I had some Canadian change, but it was in the back in my suitcase. Fortunately, the toll was just $1 and they took a US dollar. I used the bridge later during non-rush hour and there was minimal traffic.
