Free: Contests & Raffles.
A friend and I went out spotlighting one night, and I shined the spotlight on a coyote about 100 yards away. I held the light on him, and my buddy got out to shoot, and instead of just shooting from behind the headlights, he walked out in front of the truck and started yelling; "Turn out the headlights--I can't see!". Naturally, the coyote left quickly. I never hunted with him again!
I have done it a couple of times. The best times seemed to be the 2-3 hrs right after dusk and the 2-3 hrs right before dawn. I also called into the regional WDFW office to let them know the general area I was going, so if they got a call about spotlights they would know it was likely me out there (It isn't something you have to do, but I always figured if I was getting woke up in the middle of the night only to check on a guy that was legal, it would suck). When I called in they just asked the general area I would be in and what color and type vehicle I was driving.
