I agree, I think the time has passed to be checking trail cams often. I would pull it and not go back until you hunt. If you leave the area alone for a bit until your first hunt, the chances are 50/50 they'll come back. They probably will if you're in an area that's used to human activity. If you're in the wilderness, maybe not.

If you're set on keeping the trail cam out, is there a spot near your hunting area where you know they'll travel regularly, that you can get into without much disturbance? The reason I ask is that I have a spot where the deer move down an old gravel driveway in the woods every morning and nightly into a cornfield across the road. It's easy enough for me to walk 10 yards from the road down the driveway every 2 weeks, hang the camera pointed down the driveway, spray the hell out of it with scent killer, wipe and leave. I'm not actually seeing where they're going in my hunting area, but if they're following the trails I've identified, which they likely are, I'm good. And by having the camera on the driveway, I have a good low impact way of knowing at what times they're moving. You can do the same with other low impact areas you can identify.
