Hagerstown man asks why post office won’t add wheelchair accessHAGERSTOWN, Ind. Even though he’s still able to maintain his farm, if he wants to drop something off or pick something up inside the Hagerstown post office, he can’t. Because the entrance to the Hagerstown post office is not wheelchair accessible. If he needs help, Bell calls the post office so an employee can meet him on the sidewalk. That exemption did not hold up in court when a woman sued USPS over the lack of a wheelchair ramp at the Shelbyville, Indiana post office.
