You would be suprised at how many gut piles I have left in the woods after gutting a deer to make it lighter to drag out. I have returned to the stand two days later and the mess is scavengered. Its gone and to be honest I have killed a deer at the same time a gut pile was in sight of my kill. The nature of that stuff in the woods feeds the food chain, and sure isnt going to affect the deer.

Carcasses area different case. I dispose mine in places out of sight and where othersdo not hunt. Buzzards pick them clean in a day and the yotes, foxes, and even bear will deveour them within a day our two leaving only a skeleton. This usually gets dragged off out of site by dogs or yotes.

Sides of roads is just lack of commonsense and irrisponsible to the land owner or neighbors who have to see them. Dump them out of site and let mother nature and the food chain dispose of them
