Rules of Courtesy

When entering a collecting area every collector should observe several

rules carefully:

① For your own protection get permission to enter and collect on any

private property. Such action also will help to assure your welcome if

you wish to come back again.

② Leave the gates exactly as you find them, open or closed. Do not climb

fences that may break or sag under your weight; crawl under or go

around.

③ Don’t litter, even though far from any house or other buildings. Do

not disturb the owner’s equipment, stock, or planted areas.
