Danger is my middle name lol. It was seriously dangerous on Wednesdays and Saturdays when they had the course full as our house sat at the end of a dog leg and if you hit it straight they would find us. I was amazed at how many balls found our property until I played the course and hit one into the pool. I knew this as I retrieved it when I got home lol. Most are ProV1's and are basically brand new so yes they are worth something. I used them for practicing my putting and chipping after hours when the course was closed which was one of the perks living next door.
