I have hunted all over the US and even went to Africa once.
Generally speaking the eastern states are closer range and western states are long range. Now there are lots of exceptions, there are places here in Idaho where the forests and river areas are pretty thick and hunting is often less than 100 yards.
I hunted Hogs in Mississippi a few years back and I can tell you that having a high power scope would hinder you hunting. Down there many people used Shot guns and big bore lever actions. If you where to take the same guns out here to southern Idaho you would have to be really good to stalk up to an animal in an area where there is literally nothing to hide behind for miles and miles. In the Owhyees (south west of Boise Idaho) there is lots of pretty flat land with no plants higher than 2-3 inches tall for as far as the eye can see in any direction.
