Were you walking or still hunting? I usually see more squirrels in a treestand or just plant myself somewhere and hold still. Walking will cause them to scurry and hide on the back side of the tree. You probably walked past quite a few in your travels. Do you have a call? If there's a hawk in the area you won't see any. I've had those days when I didn't see a squirrel all day also? Maybe you are onto sumpin with that whole orgy thing? LOL!!
