Ahhh, that's so cool! I love stuff like this, I'm sure you are learning so much there!
As for the bike system I TOTALLY agree. Unfortunately where I live in Texas everything is so spread out that a bike system would be ridiculous, but I have heard of such things in more major cities like Austin and Denton. I know there are a lot of places in Europe that have them, in fact I plan on utilizing quite a few of them when I travel Europe this summer. Specifically Berlin, I've heard it is a beautiful city to bike through.
I have a question! Food! The good, the bad, the ugly...the surprising! Tell all, food is such an interesting and particular facet of culture, I'd love to know what discoveries you've made, both pleasant and unpleasant.
