Yes, those plants were closer, like 1/2 to 3/4 mile apart. Was just taking a guess from memory. Ask the mailman: Ex. Address of (21000 Mound Road minus 5000) ÷ 2 = 8,000 = 8 Mile Road and Mound Road, center of intersection. (19000 Mound Road minus 5000) ÷ 2 = 7,000 = 7 Mile Road and Mound Road. Each mile 2000 in address.
