Just looked at a google map and there is a “High” listed on old hwy 56....but there are so many little wide spots in the road scattered around that it’s hard to keep up with all of them...it now has been bypassed by Rte 82.... I live just west of Bonham.. I expect their mailing address was Honey Grove...”The sweetest little town in Texas”!

their farm was just south of the highway and to the left of the county road.
