This guy wasn't your typical dummy tourist, he runs on the island all the time, thousands of miles in fact. Just goes to show, accidents can happen to anyone at any time!
Same sorta thing happened to Indians and Frontiersmen alike, as long as humans and dangerous critters are sharing the same real estate things can happen..
Closest I came was back in college at a Field Station in the Adirondacks, used to run three miles up and three miles back along a forest trail every evening. Ran around a big rock outcrop along the trail one time and stumbled into a big male black bear, right there, coming the other way. First I saw was was that head swinging down and around as it turned to run, it huffed and woofed its way over the next hill, kicking leaves up with every bound. If it had been a sow with cubs, or just in a bad mood, I coulda got seriously chewed on. No earbuds involved.
