I don't know about your state hunting regs, but in TX, just because it's gun season does not mean you have to put your bow up. Like someone else said, this is your challenge man, GO FOR IT! I would love to take on that challenge one day. What's good is that alot of the hard part is already done.
1. You've located a monster.
2. You know where and when he's coming from.
3. You know where and when he's going.
Now you've just got to put that arrow in the right spot. You'll be so proud when you do.

I look forward to seeing your pictures of him.
