Q: i'm headed to a concert today but my goal is to be in Toronto by three thirty, I'm coming from Hamilton. How is the traffic around that time? Should I leave earlier than two o'clock?
A: 90 minutes would cut it a bit close. Unless you need to be in Hamilton till 2:00, I would leave at 1:30. You may find that the first 30 km take 15 minutes, and the last 4 km take 45 minutes.
