I'm only assuming because of the way the deer population is here in Maine. If this were NY, back where I grew up, I wouldn't blink an eye. Most days here its a good day if you even see a deer. I know a group of 5 guys that went hunting up in northern maine to their usual camp for 7 days last year. They saw 3 deer all together, all week. And I've heard similar stories from other guys.
Am I envious? you bet! But I'm also suspicious. Nobody kills that many deer up here. If he's doing it legitimately, then he is probably the first and last I'll see thats that good.
