As you can see, the vast majority of my biking experience has been in Texas, but I'm not really looking to stay here.
For examples of what I mean, San Antonio, TX has a nice multi-use path that rings the city that I think is nearly 80 miles long. Austin, in my experience, had very little in the way of paved paths longer than about 7 miles so I rode them repetitively until I was bored to tears. The Dallas/Fort Worth area has the Trinity trail which, while not always paved (crushed gravel) is extensive. Houston has the paths along the bayous. And Boulder, CO had some nice paved trails as well. As you can see, the vast majority of my biking experience has been in Texas, but I'm not really looking to stay here.
