This morning I got out in the woods. I didn't see anything from my stand, but there is evidence around the deer feeder that they've found it.
Below my stand trickles a small, intermittent creek. It's got a sandy gravel bottom and in my area it cuts through extremely thick woods. Here's a picture of the creek. You can click on the pic for a larger image (640X480)
The deer use the creek as a travel path. The thick woods on each side and the undercut banks make it almost impossible to see an animal as it traverses the creek bottom. There's one area that's extremely sandy, about 125 yards from my stand. When I'm in the woods I'll walk down to the creek and check the traffic. I always wipe out the tracks so that next week I'll know which tracks are new. Here's a representative sample. The cartridge in the photo is a .30-06 for scale.
What I don't know is what time of day the deer are using the creek bottom. If it's at night, then that knowledge does me no good, because night hunting is illegal. If it's during the day, knowing when they're moving would be a big help.
