This is one thread that I can actually give good advice to lol. I am 20 years old and when I was in high school I was on block schedules and still missed some days to hunt. This is what you do... If your son really wants to go he needs to talk to his teachers in advance and find out what he is going to miss. A lot of times teachers will give you an outline of the lesson if ask. This way you will not be that far behind when you come back. I would encourage you to take your son if he really wants to go!
