If in one corner of your "living room" there is a remodeled bookcase that houses all your calls...and anything else related to calling coyotes, except the guns...you might be a coyote hunter.
If along another wall across that same room, is a work-table covered in cowhorns/antlers/drill/drill bits/Dremel/and Dremel tool parts, for making your own calls...you might be a coyote hunter.
If every Spring, at work, you are introduced to all the seasonal help as "the Coyote Man" by the head saleman...and he insists that you give demonstrations almost daily...you might be a coyote hunter. (true, oh so true)
If you can't see out the rear window of your pickup, because it's covered with decals that say things like...Carver Calls; TT Custom Calls; Arky; Verminator Calls; PredatorMasters.com;ect...you might be a coyote hunter.
If you travel 30 miles (1 way) in order to pay a traffic ticket in a neighboring county...{and although due to your health, you haven't been able to hunt all winter}, you take along a howler; a distress call; binocs; & your rifle & box of ammo, AND insist on driving only dirt roads in hopes of seeing a coyote out mousing in a field...you might be a coyote hunter. (true story of this morning)
If you do what is described in the previous example, yet the only thing you see is a flock of about 200 turkeys feeding in milo stubs 1/2 mile away from you...and let out a lonesome howl just to watch the reaction of the flock...you might be a coyote hunter.
If while travelling the highways & biways, making deliveries for your job...you have at least one call in you van on which to "practice" your calling sequences...you might be a coyote hunter.
If you can spot a standing coyote that's 200 yds off the highway, while you're traveling 75mph...yet you didn't notice the oncoming Highway Patrol car in your rear view mirror...you might be a coyote hunter.
Most of what everyone else has posted, I've been guilty of!
