It's a good time of year to keep the trailcams in use. I use mine a lot and have some thoughts:
1. If you use a deer, do what another poster mentioned about staking it down.
2. Coyotes are very leery of the white flash, but fox and everything else don't seem to be.
3. If you use chunks of meat, make sure they are small chunks, otherwise your bait will be picked up and removed quickly.
4. Think about how you place the bait and the camera - try to get broadside shots of the critters. If you have big chunks of bloody meat, put them down a stump or behind a log.
5. Begin with fresh batteries - the cold is heck on battery life.
6. As always, avoid pointing the cam where the sun is shining right in the lens, it will screw up some potentially good pics.
7. I picked up a sealed bag of that gutpile in a bag at the store and I swear I could smell it through the bag - I'll be surprised if it doesn't bring something in.
8. You'll get lots of birds unless you really hide it - I'm convinced crows can see through anything.
9. If you're hoping for coyotes, set your cam and leave it for a while to keep the scent down.
The first pic is an overlay of all the critters that came in to venison chunks on a wire, the second is a neat red-tailed hawk pic, the third pic was a pleasant surprise I got one day. Good luck.
