I only have one dck at the moment, and I have taken her to the park via subway. Her parents love the idea. When my other two start in August, we won't be doing this, as I will not feel comfortable crating three children under three onto public transportation, and I am also uncomfortable transporting them in my own vehicle. Thankfully, I live downtown in a fabulous city with tonnes of amenities within walking distance. If I were more isolated, I would likely suck it up and drive them places.
