Crunchy snow is the worst... They, predators know that there are no 183 pound cottontail rabbits.. crunch crunch crunch it OVER!!!!!!!
You counter this by just getting where it's legal and call..They will come to you..
Also your going to go out in snow and say...Wow what a nice night, no wind, don't need a light, and your say to yourself..."I'm going to kill a lot of critters tonight!" then you end up seeing JACK______.
Then it's going to be windy and foggy and the critters will come to any sound you use.
Also....learning too it's not so much as the time of the year but what time you are hunting that counts.. IMO seems like I call in MORE predators after 10:00 PM vs 5:00 PM in the winter when it's dark...However I do call them in then too...
So no matter what time of the year you go. there are going to be times your going to call nothing... Then there are going to be times that gee..They are coming to all my sounds!!!!
The predator hunters that hang in there and not get frustrated and quit are the ones that will get shots!!!
