I have really enjoyed dialing in my .22lr and .17HMR here recently and have shot some squirrels, but all in the evening. Here in VA there seems to be a flurry of activity about 35-40 mins before sunset. When are the squirrels active this time of year in the AM? Is it right at first light or an hour after etc...Not much happening midday I presume? Thanks for any and all help!
