I will be completely honest, I don't pick up anything. While I don't feel like I should have to deal with other peoples crap all over the course, I also don't feel like I need to pick up after them either. They can deal with their own mess and hopefully when they see their crap on the ground they will realize they suck at life and stop throwing their crap on the ground. While picking up their stuff makes the course look nice for a bit, I feel like it sends an open invitation for them to throw more crap on the ground because they know someone else will pick if up anyway.
