This is a 74 mile loop that will take you over the Bobby Hopper Tunnel on I-540. You will go down Warloop Rd and again, if you have a big bike (larger than 650), get the Warloop bypass here
other than Warloop, this track is big bike friendly, all county dirt roads. There is fuel and food at both Mountainburg and Winslow. There is some pavement just before you come into Winslow and for abt 6 or 7 miles east out of Winslow.
