Nelson, 51, has been working at Coolidge Park for seven years, and drawing attention for his dance moves for the last six years.
"It's all about enjoying what you do and that's the way I feel," Nelson said told a local TV news channel. "[It's] clean fun. It's nothing like doing any bumping and grinding."
However, not everyone agrees. Park visitor Melissa Parsons filmed one of his dance sessions and posted it online.
"As a parent and seeing all the parents that were covering their kids eyes and turning their heads away, it wasn't something you would expect to see in Coolidge Park or anywhere from a grown man, especially a man in uniform," Parsons told NewsChannel9.com. "He went all the way to the ground, he came back up from the ground, he was grabbing areas that you would see on a rated R movie."
The raw video of Nelson's dance shows him at one point lying on the ground with his legs folded under his body while he seems to pump his pelvis towards the sky.
