I have a foundations quad, but it is almost impossible to get through a regular door. On our way to the park, there is one place on a walking path that is a nightmare to try to get through. Sometimes I walk several blocks out of my way to avoid having to maneuver there. I am wishing I could get a runabout instead. Just a caution. Measure doors. I have good-sized doors, but it is still almost impossible even without the children in the stroller.
