@bobsal u1553115,
I usually lose em nearest a drilling rig. Since rigs are messy gizmos that spit mud and water all over the surrounding 50 ft radius, Its easy to have a phone get covered over with muck and sand.
AHH if only they were phone seeds, Id be a zillionaire.
Although, I havent lost one in about 2 years. The flip phones were the worst. They would slide like little sausages and sometimes into the hole
