Congrats on commuting in. I think you will find your daily travel so much more enjoyable overall. I commute into my hospital whenever I can. (many of my days are 16 hours so I don't on those days) It's just under 7 miles for me, although we will be moving soon and then it will be around 10 hilly miles each way. I'm lucky that we have full locker rooms with showers, towels, soap, scrubs(I don't have to bring clothes)... just had to stock up on shampoo, comb, deodorant and yeah, extra undies. Can't go walking around in those thin OR scrubs with no undies.
They love it when we bike in. We actually have an incentive program to ride in. 35 rides gets you $50 in your pay. There are bike lockups everywhere, mostly in the parking garages. I see people/visitors with their bikes in the halls and in the elevators everywhere. Almost every employee area has a bike in it when you walk in.

On a side note, Python, I still love that bike of yours woman. What an incredible find. She is just beautiful.
