That's a smart plam, noahhh. I learned about carrying a back up rifle years ago. I drove 6-700 miles on a moose hunt without the proper rifle. I had to go to the local hardware store and buy a rifle.
I bought a M94 lever for $240 (oh, darn! Cause I already had one...at home). That year's meat was expensive. I took a calf (350 lb?) with an archaic 170 gr. CIL FP factory load.
