Good Question
The reasons Pa. guys don't hunt much during daylight has several answers and some were mentioned.
-More action during the night time, predators more active in Pa.
-Most folks work during the day, giving way to night time calling throughout the work week.
-Every day, more people in Pa. outdoors, farmers, hunters, joggers, cross county skiers, firewood cutters, hikers, atv riders, snowmobile riders, trappers, fishermen, ice fishermen and so on. Lots of human activity and the critters seem to avoid that. Folks tend to hole up at night and critters come out. Not much 'free range' in my area.
-Most guys learn to hunt at night in Pa. (because we can) and we tend to stick to what we learned or when to hunt or have time to hunt.
cj, if your area permitted night calling and you did it as long, as much, as some members, you may have different perspective on night calling. (don't take that the wrong way, am not stepping on your toes)
When I am mad at 'em and want to slam 'em, I will do 40%-50% of my stands during day light hours for Fox/Coon. I am 100% day light calling for Coyote.
Personally, I do alot of day light calling. When I was working a full time job, I would call early daylight, then go to work, may make a stop or three on the way home from work in the dark. Weekends off at the time, I would work the weather fronts as they moved, day or night. Even called my work and took 'sick days' to work weather fronts during daylight hours.
Winter conditions, extended cold and/or extended snow cover, I hunt daylight (along with night hunts) but critters are on the move during these hard times.
cj, we live in two different hunting method worlds...lol.
