They'll be back. If there were that many deer in the area, then it's a highly popular spot and they won'tbe away for long.

I recently have too, second guest my spot plenty of times. There were three or four times this season I hunted 3 straight evenings without seeing a deer but the fourth night I would see around 10. It's all about being there when they decide to come back. You ain't going to see'em from the couch. So stick with it, you'll get'em.
