Yes indeed, Ft Worth does have it going on! We're planning to ride tomorrow AM from out home in central Arlington ( the heart of the '013' ) to the Hurst/Bell TRE station, take the train to downtown, explore the South Side/Hospital historic district, and ride the train back to Hurst and then on home.
My favorite section of the trail is from Gateway Park to downtown, then further west towards Lake Worth.
Yes, if the TRE ran on Sunday it would make the perfect Sunday ride into downtown for a cuppa coffee.
