Let me just hop on my 10 speed and peddle on down to the airport in my slacks, sport jacket, and dress shoes with my computer bag and and carry on stuffed into a couple bike bags. Oh, and it's February and I've got a 6.30AM departure. Seems pretty practical.
biking to the airport is obviously Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!) in mhk. but hey, putting a bus system in mhk is marginal at best as well. public transport of any kind is marginal at best in a midwestern american town of 50k.
in fresno, biking to the airport would have been great for me, yesterday, and would probably be useful in general. lots of people go to airports for reasons other than flying. hundreds of employees, me yesterday to rent a car, etc. plus the airport isn't out in the middle of nowhere, there's offices and crap all around it.
