make checklist so you don't forget
-Let your neighbour know (month advance, then one week and one day before game)
-let Police know you have game at your field so They would know what to expect if they get call
-Set Boundaries for field so you or your friends don't accident wander into wrong place
--use ballistic approved glass, paintball mask, or Mesh mask.
--Keep mag out, and gun safety on until game start.
--Make sure there is no fragile thing like window, and so. (To prevent any risk of cut from broken glass)
my english is bad. however, It don't make up different on your ignorance.
