When my wife and I moved we completely changed what we were looking for in a house/community. We wanted a Main Street style town. We used to love master planned communities with huge houses. In our small, Main Street style town all of our kids can walk/ride to school, we have two grocery stores within 2 miles away, and all our doctors are biking/riding distance. It's changed how we live. We sold our second car. We own so many bikes. We are more active.
Cul-de-sac looks really promising. I've been following along and am excited to see what they create. We need more experiments, even if some don't work out.
