After getting our toddlers out of infancy we are back to car-light-hood. This morning we'd planned to head to a friends house about 20 miles away and I went out to start up the van on a cold, Denver morning and the van wouldn't start. Too cold. Back when I had two cars I would have jumped one with the other, alas I had no second car. I came back in and posed the problem to my wife, five year old and two year old. My five year old just suggested we take my bakfiets. ("Dad, let's just take the bike." total win!) A tad too long of a trip for that, we waited about 20 minutes for the sun to crest and warm up the street and then the car started.
Reminds me that single car ownership requires a few extras, like, say, a portable battery jumper.
