I plan on taking my son out of school for at least a week in the fall when he is old enough to hunt unless for some reason he is struggling to get by in school or something.
Somehow I think spending a week in the mountains hunting elk with his dad will stick with him longer in life than spending a week in history class.
I rarely missed any school and got in plenty of hunting as well, and my mother always stressed that good grades were money in the bank and that turned out to be true when it came time to apply to college, but I think with a little work you can have your cake and eat it too.
I think teaching a kid to plan ahead and get his assignments done and take care of business for taking a week off of school is a very important lesson that will actually benefit them in the long run.
