First, I tend to agree with the OP. More guys are going farther. Still a lot of lazy slobs too. As for the rest of the whining about all the reasons it's worse...
Natural evolution.
Have you ever seen anything of value increase in availability over time?
Will we ever see more open space?
Technology improves. Hell they even have 800yd muzzleloaders now.
Fact is most of you are only complaining because it isn't getting easier for you to kill bigger or more critters.
If we need anything it's better ethics of our average hunter.
If game is scarce, self regulate take, no matter if you are a "meat" hunter, or a guy buying two tags so you can fill good about filling one tag before trophy hunting with a second.
Stay on designated trails if you use bikes/quads. Damn sure is plenty of space in between trails if you do.
Just because you have a $4k sniper rifle doesn't mean you can make a 500 to 1000 yard shot, nor does it mean you should.
Using primitive weapons that lead to more wounded animals because they are less effective, just wastes game.
So, in the end, be a better human being and we will all enjoy better hunting, even if we don't fill tags.
