Driving Range by grandmaR
Across from the Sombrero Resort and next to the road and the Golf Course is a driving range. There is netting from the top of the chain link fence up to the level of the power and telephone lines. We saw someone picking up the balls with a kind of ball sweeper machine while we were eating dinner. I can't find anything out about it on the internet.
