Bicycle Commuting to Work

Is it practical to commute to work via bicycle? I've been doing it for the last 2 weeks and here are some suggestions/observations. 1) Storage - you need a place to store the bike at work. Our downtown office has a storage room in the basement that is perfect. Most buildings won't let you bring the bike in the elevator; 2) Shower - you'll need a place to shower. I joined a small fitness center in the building next door; 3) Clothes - I roll my suit into a garment back and pack in a backpack. If rolled properly, no wrinkles; 4) Meetings out of cab range. I joined ZipCar so in case I have to drive to a meeting, I can. The service works great. Downsides? Things change so the biggest hurdle is when I need to meet someone for a drink or event after work. Fortunatley, I only live 3.5 miles from the office so I can cab it or take public transportation easily. So far, I enjoy the bike commute and the extra miles i am able to achieve. We'll see what happens when it gets colder and darker.
