Jen and I were out for a walk in High Park to see the cherry tree blossoms. I think half of the city had the exact same idea, except that many people drove there, gridlocking the roads around the park.
It's so much easier to walk, cycle, or take the subway to the park. No getting stuck in traffic, searching endlessly for parking, or worrying about getting a parking ticket.
Parks are so much better when they're not full of idling cars, angry honking motorists, and smelly exhaust.
