well if money is an issue ,I WOULD NOT WASTE IT ON A DECOY.
THIS IS WHAT YOU NEED TO HUNT ANY ANIMAL.
1. WEAPON AND AMMO
2.TAG, LICENSE
3. PROPER CLOTHING AND BOOTS FOR WEATHER AND TERRAIN. it is miserable hunting when you're freezing.
4. knife so you can feild dress your kill
everything else is up to your personal preferences. though I would suggest packing some TP for when nature calls. rocks and sticks will do in a pinch but it ain't my first choice
