Most years I hunt bears with big groups.Alot of planning and a ridiculous amount of work goes into the drives themselves so most groups will frown on anyone who refuses to shoot a bear that goes past the standers.I don't have much interest in killing any bear but I do like the anticipation of hearing the shots ringing out and seeing the results of a well-executed drive.As a result,I drive every drive and hope that I don't cross paths with any bear,big or small.I've been on hand when a couple dozen bears have been killed and the smallest bear I've ever witnessed getting shot was an 80lb cub but that was only one time.Most of the bears range from 150-200lbs.I'll never "get" the PA bear hunting mentality of shooting cubs.
The season is set up so that most of the sows with cubs are already denned but depending on available food,that's not always the case and some sows and cubs get killed.If the sow is killed,the cubs have a instinct to den on their own and the majority will survive.Several years ago,there was a sow and 5 cubs behind my buddy's place.The sow and two of the cubs were killed but the remaining three survived til at least the next fall.
I don't want to kill a bear bad enough to shoot a cub but realize that it's just part of managing them.
