I saw on Facebook that they are beginning work on a west side Brays extension that will take it from the west end at the Fiesta Mart on Gessner northward along the bayou up toward Richmond in the Westchase area, meaning you would conceivably be able to ride from Terry Hershey down through the Walnut Bend neighborhood (i do every day on my commute), carefully cross Westheimer (yikes) at Rogerdale, and make your way down to Richmond and pick up the Brays trail and ride it all the way to the Med Center. I'm game for that.
Wish they'd install some pedestrian/bike bridges over roads like Westheimer though. Seems like a no brainer to me. But, then, things that make sense rarely happen.....
