I love my quint Runabout. It's narrow enough that I can get into public places. The wheels are big enough to go easily through snow/ice. Because of it's "antigravity" design it's easy to tip the front wheels up to get up curbs. Even when I've got it loaded up I can push it with one hand.

They are expensive, but they are a quality stroller that will last for 20 years. Definitely worth the investment for me! I walk to the school twice a day and go out daily in the summer, so I need something sturdy and functional in winter weather.
