You are spoiled. Rememeber those Philly commutes? 10 minutes to the train station. 10 minutes waiting for the train. 30 minutes on the train. 10 minutes to walk to the office. And its 20 degrees and you are walking through slush. Remember that its like to get to work with cold, wet feet? And that is an easy commute.
One thing people dont factor into the desireability of SD is how easy our commutes are for a metro area as large as we live in. Its another positive factor in our quality of life out here that often is overlooked.
