You ^ are awesome. You are blessed that God gave you the gift of legs to walk and you don't take it for granted. Don't ever give up!
Although I could purchase several ATV’s I will never own one and I walk in every time. On some days my walk-in is 1.5 hours, my pack is heavy, I climb STEEP mountains well before sunrise, go around 100 acre clearcuts, and sometimes carry-in my scent free clothes to change into when I reach my climber. When you do harvest a mature buck, you are satisfied in KNOWIING that you earned it.
over the last 25 years, people riding ATV's/motorized vehicles into their stands has improved my harvest of mature bucks. Many mature bucks have been spooked by motorized vehicles right to me. In some of my stands I have watched those bucks come great distances, across properties, through cuts and right to me. Soooo glad people continue to ride their motorized vehicles to their stands, lol!
If you have a medical condition and can't walk, that's a solid reason to consider using a motorized vehicle. If you guide people for which you are responsible for their safety over GREAT distances that's another reason for potential use of motorized vehicles. If you are hunting in wolf territory, that's another reason, and I am sure there are other justifiable reasons.
Unfortunately God took away some people's ability to walk. Thousands of people would give ANYTHING to be able to walk again. God blessed me with the GIFT of walking, running, riding a bike and I am NOT going to throw it away because I choose to be lazy.
