The Fencewalker

At North China Park one can often see the fencewalker these days. The man drives a black car up to the Great Northern Way side of the park, gets out, and hops up onto the chainlink fence. He squate while he gets his balance, and practices balancing on one foot and letting his other leg swing loose. Then he gradually works up to standing and walking. If he missteps and has to come down, he starts over. He is moderately good at this, but clearly aims to perfect it.
