depends on which course im playing at. There is a cheaper course that i play at sometimes and its always top flites and other low end balls. I love going to the higher end golf courses because most ball are pretty nice, and most times they are only a little ways into the trees.
When I marshalled, I found balls all the time! Now I barely look for mine, let alone find anyone elses. Unless I know for sure that it doesn't belong to someone who may come by in a few minutes looking for it, I leave them alone.
