Here is a list of things that I figured out would be nice to have on a Prairie Dog trip.
More than one rifle
a wide brimmed or boonie hat
gun cleaning equipment
spotting scope, binoculars
range finder, would be a nice convienence
plenty of water
some paper plates & markers to make a sign, in case you join the Varmint Hunters Association & want to try for the down range club
, btw, you will need atleast one witness that is also a member of the VHA
As someone else stated you can spend as much money & time on this as you want.
