no, I'm in for the day, but most days, squirrels are like most any other game animal, moving early in the morning for some period of time, then again late in the day. if, when, and how long they are active is anyone's guess. I've been watching squirrels from treestands for 35 years, been hunting them with dogs for over 10. the only thing I can say with any real certainty is that there is positively no rhyme or reason to when or how long rats are active. none. go hunt and have fun. if there are lots of squirrels and plenty of food on your place, then you will probably see some squirrels every time you go out.
squirrels practically always know you are there no matter how stealthy you think you are, full concealment blinds notwithstanding. move slow, be quiet, wear camo and your odds of getting into good range for a shot go up. or get a couple of squirrel dogs.
