Mode share by trip miles and trip frequency in Chicago and Cook County
Two tables in this post. Data from the Chicago Metropolitan Agency for Planning’s 2008 Travel Tracker Survey. Download source file (pdf).
Table 1. Number represents share of trip miles taken by that mode. So in Central Chicago (which seems to comprise neighborhoods as far north as Uptown and as far south as Hyde Park), 1.4% of all trip miles are by bike. If 1,000 people take 100 trips of 2 miles each, then 2,800 miles will be by bike.

Brooks B67 leather sprung saddle
So far my longest trip was 40 miles on this saddle. It molds to your butt like Birkenstock sandals mold to your feet. The springs make the bike ride a little more comfortable and more fun (weird, because you bounce up and down on them). It also looks gorgeous. Comes in 3 colors - I got black.

Bells can be quite useful, especially to tell people in front that you're passing them. I like the ding-dong bell the best. It makes a solid DING and then DONG on the spring's return.

So far I haven't had a flat with this tire. I've used Continental Gatorskin and Panaracer T-Serv, both of which have had flats (same Chicago streets). The Gatorskin has less tread than both, and wears to a slick surface faster.

Books

Making Maps: A Visual Guide to Map Design for GIS by John Krygier PhD, Denis Wood PhD
If you are going to make a map, whether it be hand drawn or digital, you should really give this book a read. Then read it every time you make a map. It will help make sure your maps are laid out sensibly, in a way that others can easily read, and that it doesn't include fluff or unnecessary data.

Instant City: Life and Death in Karachi by Steve Inskeep
I reviewed this book that the publisher sent to me.

Sustainable Transportation Planning: Tools for Creating Vibrant, Healthy, and Resilient Communities (Wiley Series in Sustainable Design) by Jeffrey Tumlin
I was sent a review copy. I'm really excited to open it up and start reading because I've been disappointed with textbooks in the past that don't focus on bicycle and pedestrian planning.
