My lem 8# .5hp hasn't slowed me down grinding. Takes me longer to clean it than it does to grind all my deer trimmings. But if you have the space and budget for it, wouldn't hurt to go larger.
Hopefully. That would mean things should improve in the next couple years... As long as all the little bucks don't get shot! The population seems to be good as far as total numbers of deer.
I hunt in the northern part of the same unit as you. Been seeing a lot of does and spikes. Mature buck sightings on my trail cameras have been less and less the last few years. I think the one deer limit definitely hurts the buck population.
Social media seems to stoke the fires of narcissistic traits in people. People think their opinions are so great we must all want to look up their nostrils as they pontificate into their selfie cams.
