If I am going some where where I am staying at a lodge, then I bring a back up, usually something a little different to use if I fill the primary tag. For hunts where its a hike in or fly in, I bring a second scope with rings pre-zeroed, a 6x36 or 4x33 is pretty small and under a pound with rings. On two rifles the back up is a Ruger NECG peep. Its been more than 20 years since I had an issue, never with the rifle, but I did have a scope 20 years ago go to crap at the zero check before the hunt and it was before I brought back-ups . 5 hour drive home, 5 hour drive back to the lodge, 2 hours sleep in the car before heading out to hunt, was a long first day.
