How did Hart get his farm back?
Roger swindled Hart’s grandfather out of his land. When he found out Hart was his son, he gave the farm back to him. Hart didn’t keep up the tax payments, so Dylan bought the farm at action. Roger bought the farm back from Dylan, but Hart had left town by this point. After Dinah & Hart got Roger committed, she got control of Roger’s holdings & sold the farm back to Hart for $1.
