The course in Sedona, AZ has a "no penalty" drop rule for OB shots. Too many rattlesnakes surround the course.
Not sure it was a formal rule, but we practiced the same at the public course in Midland. The "rough" was untouched natural desert. Rock hard dirt, lots of snakes, and even more cactuses. Every type of native plant growing out there had thorns or stickers. Plus there was a huge prairie dog town in there. There would be times you hit a perfect shot down the middle of the fairway and your ball would just disappear into a prairie dog hole.
when working on the prison in ft stockton we would go play the local course with the project engineer, he was a golfer while the rest of us were beer drinkers.
you had to watch where you stepped due to the snakes, guy that ran the ball cart on the driving range said he picked up one or 2 a week when gathering balls in the cart.
we killed at least 3 a day on the job, bigun was almost 8', was in a stack of lumber one morning. labor foreman carried an 870 in his cart.
