I should just go check it out since I'm not far from Farmersville. From poking around on the web it looks like there are several sections that are bypassed with local state highways. And it looks like some portions are dirt, which are obviously going to turn to mud when it rains. I'm just wondering how extensive those dirt/mud sections are likely to be.
Edited to mention this is a 130 mile rails-to-trail route from Farmersville, TX to New Boston, TX. More info here:
