FM455 is a great route far north of DFW. If you take 75 north to Anna, you can exit to FM455 and begin riding west. Follow it all the way past I-35 to Forestburg and then get on FM677 north to Saint Jo and beyond to the Illinois Bend. Turn right to continue on 677 and roll throttle on the downhill straight to the Taovoyas Indian Bridge on the Red River. Then turn around on the Oklahoma side and on the way back, veer left off of 677 to head south on FM373 to Muenster. After a stop at Fischer's Meat Market & Grocery, continue on 373 south to FM922 east and head back. Drop down 377 to FM121 then continue east.
