I took a video with my dig cam the other night...a doe crossed the river, with this buck behind...the video quality is degraded after the upload and you can't hear the "grunts" of the buck...notice his head down, sniffing what is an estrus doe(i tried to show through the trees).
This is just the type of thing you see bow hunting....and why I do it(for those that don't). A bobcat was seen at close range from the same stand the weekend before.
