Pretty much every golf course architect has encountered his share of wild animals and other dangers if he has walked enough sites. Often enough we are out there by ourselves, which is just stupid, but we don't usually worry about it.
I have encountered poisonous snakes of various kinds, alligators, wild boars, kangaroos, water buffalo, bison, elk, and bees nests, all of them potentially dangerous. Deer hunters, dynamite teams, and Latvian army guys, too. Still, the closest I ever came to severe injury was bodysurfing on a site in the Dominican Republic, when the guy next to me, a hotel executive, did a header onto a hidden coral reef, and we had to medevac him back to the U.S.
However the most startling was encountering a naked homeless man on a site along the river near downtown Omaha. Didn't know what to say there. He did not appear to be in possession of all his faculties.
