Try going to the schools around 7am on a Saturday/Sunday mornings.I carry and empty 5 gallon bucket where I store my water & pro-pointer and maybe something to eat,and I also pack out any junk I find in the Tot-lots,I found out that it helps if you put some rusty wire,some broken glass,and maybe some razor blades in your junk bucket so if someone asks what your doing,you can show them the crap your pulling out.
