Let's just say Chris Dempsey, 60, likes being vertically challenged. Since the Sun City Summerlin resident got into hiking mountains a few years ago, he has been known to trek the wilds an average of four days a week.

In 2004, he logged 1,205 miles. In 2005, "only" 1,162 miles. It is all the more impressive when you realize much of that involved uphill climbs.
