Ft Worth seems to be a bike friendly town. I would prefer the jogging trails along the Trinity River, where bikes are also welcome, instead of on the city streets....where a lot of the locals seem to drive large pickup trucks!
Several U.S. City are putting in bike rental stations. Ft. Worth had 30 stations now.(thourghout downtown, the culture district and near the university) The first 30 min are free...They lease for $8 for 24 hrs. $20 for 7days $30 for a month or you can buy a yearly membership for $80. I am not sure if they have caught on. I noticed when I was in Paris, France that a similar system had really caught on.... and the locals were riding them to work. Would be nice if it caught on here.
