Neither rain, nor biting cold, nor sleet, nor oppressive heat kept Richard Lewis from his appointed rounds — and the record book. The 64-year-old Lewis entered the Guinness Book of World Records for playing and walking the most rounds of golf in a single calendar year when he completed his 600th round on Sunday. Lewis, however, had to delay his momentous round a few hours as the TPC Four Seasons Resort Las Colinas course in Irving, Texas, which hosts the annual PGA Tour's HP Byron Nelson Championship, warmed up. "It was 25 degrees at 6 a.m. When we teed off at 11 and it was 33 degrees, with 10 mph winds and a chill factor of 27," Lewis said in a phone interview. "It was a tough day for golf. You can play in the heat. But I'll tell you, no matter what your skill level is, unless you're a touring pro, playing in the cold just makes everything so tough." Lewis, a member of the Four Seasons Resort and Club Dallas at Las Colinas, played in everything Mother Nature dealt up this year — and will polish off 2010 by playing 36 holes on Monday and Tuesday, 54 each of the following two days and 18 on New Year's eve. That would give him 611 rounds for the year — and 11,000 holes of golf (counting the two he played before being called off the course because of severe weather conditions). "Unless they pull me off the course — and lightning is the only thing that will stop me — I will get in 611 rounds," Lewis said. "I would say," Four Seasons Club Manager Rob Cowan said, "nobody in the 27-year history of the Four Seasons has gotten more out of his membership than Richard." Cowan is most likely right. Lewis said when he retired last year he told his fellow workers that he'd play golf every day. "And they said there was no way I'd play every day, because I'd go on vacations and I'd have bad days," Lewis said.

It's a record: 600 rounds of golf in 2010, and he's still going
