The problem with the DFW plan is they don't have the funding for it, so it's really just a plan which may never materialize, but at least they have a plan.
With gas prices going the way they are, perhaps the plan will get more funding. If they were to complete the entire plan, I could ride all the way to the airport via bike trails, but at significantly longer distances. Even if they complete it, I'll probably still use the same route I use now.
