I have only had run ins with 1 warden who for some reason decided He did not like me, see him at least once a year (usually hunting) and he does everything short of a cavity search. Even though i dont care for him I still let him check everything because It is nice to see these guys out there doing their job and protecting our resources.
For those of us that do support the 385 wardens that patrol our state may I suggest this:
