Nov. 30, 2009 (United Press International) -- A paraplegic says he was harassed by workers at Florida's Disney World who tried to make him lower his high-tech wheelchair from two wheels to four wheels.

"I'm not a dog. I don't want to be on all fours," Myron Rosner, the mayor of North Miami Beach, told The South Florida Sun-Sentinel in a story published Monday.

Rosner, 49, rides an iBOT Mobility System, which can travel on two or four wheels, climb stairs and drive through sand.

Saturday, security guards at Disney's Epcot Center told Rosner his wheelchair in the raised, eye-level, two-wheel position violated the park's safety policy. He said he heard the same thing Sunday at Disney's Animal Kingdom.

Disney spokeswoman Zoraya Suarez said keeping all such high-tech chairs in a lowered four-wheel position ensures the safety of visitors boarding park attractions.

Johnson & Johnson this year discontinued the iBOT, which cost $30,000 each, had low sales, and did not qualify for Medicare or Medicaid reimbursement.
