I would sincerely appreciate it, and my son would as well. It's been a frustrating few days to say the least for him.
It can be a tough hunt, the success rate on those late bull hunts isn't very high but it can also be rewarding. I'm sending a PM, might be helpful but might not be.
Question, you don't work for UPS do you. My UPS driver is out in 3C too with his son. Made me wonder.
We dove into some serious canyon country today.. Got lucky and filled another tag, my SIL connected on a small bull. Pic attached. Took us all day to get him boned out and packed out. He was getting discouraged, hadn't seen bull all hunt, just cows. He's hooked. Keep your son encouraged if you can, it's nice seeing young men get out in the woods with their family.
Edit; I can't send you a PM for some reason. If you want to send me your email or another way to communicate let me know. I'm not going out tomorrow, need to tend to some work stuff. I wasn't able to reach my buddies who are on that hunt today, they went into some rough country and I haven't heard from them, they will call when they are back on the grid. I did see two more bulls in the right a way an hour before light on our way out this morning. I'll give you the mile marker if I can, I haven't seen anyone hunting that area the whole hunt. I see them up the road a ways but not where I've been seeing those bulls. I don't want to post my cell here but if we can I'm happy to chat tomorrow.
Good luck!
