Cause let's face it... when we go for family rides we're all in search of that "blissful" ride with the sunshine, birds chirping, butterflies dancing, and all other utopian notions that accompany the fun that comes when the entire family is on the bike.

Some thoughts for next time and family route selection:
Bike lanes are good for individual riding, commuting, and direct trips. They are not as nice for family riding because of traffic volume, and it is difficult, if not dangerous to ride two abreast.
Residential roads are nice. The traffic is slower, and cars expect to travel at slower speeds. We had a minivan drive patiently, slowly behind us for several blocks without trying to pass us (though they could have if they were in a rush). I doubt you'd get the same offer on a major street. The less direct/detour is far worth it. Let's face it, if you are on a family ride, are you really in a rush anywhere? The residential roads allow you to ride next to your family members in a much more calm environment.
Routing has never been easier with online mapping tools like google maps, google earth, and mileage tracking sites like gmaps pedometer (our route linked) that allow you to share your routes (or record them for future use).
What are your experiences with family bike route planning?
