The main reason, I reckon, is future reference. I aim to eventually ride fixed, so I figured I'd just toss it in now. SF capitalized for the city, aaaaand S is my first initial (didn't really think about that until just now though). Confusion and annoyances are an added bonus!

I'm leaning towards just starting with the fixed and practicing in the park where its pretty flat and void of hectic street traffic.

Thanks for the tape tip 79pmooney, and Vegan, I love the reference to "like riding a bike".

cali_axela, good points, and I most certainly will come out for a social ride, sounds like fun!
