The Cowboys site must have been crawling with snakes. Of the probably 10 snake encounters of my life, 5 were on that (very excellent) course. Attending the rattlesnake roundup in Sweetwater as a 5 year old left an impression: I dislike snakes greatly.
Yes, one of my closest encounters was near where bridge on 5 tee is, as we walked across the dry creekbed.
Will echo that on occasion have been vaguely threatened by some "yutes." I have stumbled on passed out drug addicts and even a corpse in a golf course restroom on a remodel.
In China, where they were putting the residents out of their homes to build the new subdivision/golf course, my Chinese hosts "volunteered me" to go speak to a lady who was upset about that (I only know 3 phrases in Chinese) who proceeded to beat me with her broom. Of course, mosquitoes in that region are scary if you forget to get malaria medicine a few weeks before going. They laughed at me for being more afraid of mosquitos than snakes. And, some of the scariest creatures can be customs officers when arriving in a hostile country. In Vietnam, they called me back to a private room, but after a few tense (to me) minutes, their only request was that I pay the visa fees in cash USD, even for the rest of the team from Japan, which I happily did to get out of there.
Also, wild boar (TX), a rutting moose, timber wolves and mama bears protecting their cubs (MN), and probably some others. Luckily, only the moose came anywhere near to being hazardous to my health.
