"In an effort to combat the growing number of drivers on Austin’s already congested roads, officials with the City of Austin are developing a city-wide bike sharing program. " This bike share program should start rolling out this year (2012) Start Rolls, Growing Numbers, City'S Widding Bikes, Pedestrian Interesting, Bikes Shared, Cities Widding Bikes, Shared Programs, Years 2012, Congestion Roads
"The Mobility Authority is constructing a 10.3-mile shared use path that will run alongside the 183A toll road and stretch from South Brushy Creek northward to the San Gabriel River. The path is an integral component of a developing network of trails that provides connections between the communities of Cedar Park, Austin and Leander."
If you have a bike, find the serial number (usually in one of these areas) and have it handy for fast reporting if it is stolen. The City of Austin and The University of Texas at Austin both have services that allow you to register your bike, making it easier to identify if recovered.
