Jerry and Kathy Merritt got presidential treatment while attending church last weekend. The local couple made a 385-mile trip to Plains, Ga., to attend a Sunday school class taught by former President Jimmy Carter. The couple then stayed for regular services at Maranatha Baptist Church and had their picture made with the former president and first lady afterwards.“It was a once-in-a-lifetime experience,” said Kathy.Added Jerry, “I haven’t been a lot of places and had access to a lot of famous people so this was really unbelievable for me.”Jerry said he learned on the Internet the former president has been teaching a Sunday school class for more than 20 years.
