… there are hazards.
This reminds me of my high school days in south Texas. The golf course on the local Air Force Base had signs posted that warned you to use a club to reach for your ball, and not to use your hand … the spot of white you were seeing could be a cottonmouth rattlesnake preparing to strike.
There were no crocodilian hazards on the course, but a group of local high school students did introduce such a beast, borrowed from the local zoo, to the pool at the Officer’s Club once.
