Yes, Indiana.

There are some commuters here, but it's not very widespread yet. The city is improving the infrastructure so it will likely pick up. There is a bike rental system in downtown Indianapolis, and also downtown Carmel (a North suburb). The Carmel one has bikes similar to the Citibikes but also big trikes with huge cargo baskets, which looked pretty handy to me (I use a trailer when I need to carry a lot).

Of course we commuters stop in to LBS for generic consumables like tubes, but the bikes and accessories they sell are pretty light on commuter gear and very heavy on performance/fitness biking.

Sounds like the hobby/utility ratio is higher here than there.

PS edited to add - just saw your blog about the greenway and passing hundreds of commuters. We have a pretty nice greenway that goes straight from my home to my work; I'm also about 12-14 miles depending on which of 2 work locations I go to. In peak Summer season I'll pass maybe 50 commuters on the way in am. Home in the evening, about the same number of commuters but a lot more people on training rides, riding with their kids, etc. In chilly or wet weather, that number drops under 10; last time I rode to work I saw two other cyclists. It was 38 degrees but no precip.
You do have a very scenic commute.
