I am 74 years old, planning my first OMO elk hunt in area 37 in Wyoming. planning on driving as far as possible with an all wheel suv and setting up base camp. then backpacking as far as I can and setting up spike camp for a couple days at a time. I only have a day pack and a cheep two man tent. the Question is, Do I need 4 season tent or tents, and what is the difference between 3 an 4 season tents? Also how big of a backpack do I need? Do most packs come in two pieces one for gear and one for meat hauling. Considering my age and how many more hunts I will be able to make do you all think I should still get the best equipment? will probably be hunting in Oct. for riffle and Sep. if I ever go with the bow.
