When I was driving an '85 Ford Escort in the mid-90s, I wouldn't fill up the tank if the price exceeded 50¢ a litre. I'm not kidding. I managed to drive this way for years and years.
About six years ago, prices hit 80¢ a litre in these parts and kept rising. We hit $1 and started talking about $2. Today, I'm happy to report the price in Toronto is back in the 70s.
The 60s would be even cooler.
