In the summer of 1989, US Magazine featured Gregg as one of it's sexy "Lookers." I haven't had a chance to scan the picture yet, but below is the information that they gave about him.
Gregg Rainwater
Age - 23
Home - Los Angeles, California and Tucson, Arizona
Occupation - Actor (Buck Cross on ABC's "The Young Riders")
Body Talk - "Once I was on an elevator and a woman got on. I pressed the ninth floor and she pressed the fifth. As we got to the ninth floor I asked if she'd missed her stop, and she looked at me and said, 'I like your smile. It was worth it.'"
