What ever happened to Doug Hollowell?

When I started orienteering, Doug Hollowell won everything in our age group. He won the US Champs in M19-20 in 1982 and 1983. He won the US Champs in younger age groups in 1980 and 1981. Back in the day, if you had to pick someone who you would have figtred to win a few M21 Champs and be on several WOC teams, you'd have picked Doug. But he didn't win any M21 Champs and didn't go to any WOCs.I
