Leaving the Buick in the driveway and trying out my feet

My oldest daughter has a doctor's appointment this afternoon. What I would normally have done is just hop in the Buick and drive the 8-10 blocks. Today I have decided to try out my feet! Benefits I expect are saving gas money (Well over $3/ gallon!!), I will be saving Mother Earth the abuse of pollution caused by driving said car and lastly, the girls and I will enjoy the time outside.
