Unpleasant enough without having to....

Using a port-a-potty is unpleasant enough without having to also "Watch For Rattlesnakes".

I assume that sign is there because someone was scared by, or bitten by a rattlesnake somewhere in California and we are such a litigious state that "if you didn't put a warning sign...." you'd get sued.

This port-a-potty was at Whiting Ranch, next to the parking lot, which was right across the street from a sprawling commercial mall.   Strange...   but I did not see a similar sign when I used the rest room across the street at the Red Robin....
