This brings up an interesting ethical dilemma (that is unrelated to my original post). If I read the rules correct posted by Sniper then you can't hunt within 150 yds of a road (any road?) going through a WMA. So if you park your vehicle along the road and hike back about 75-100 yards away from the road and come across the game you are seeking. Who would not shoot because it is still within the no hunting zone? Something to think about, unless I misinterpreted the rules and regs?

If I read the rules right, If your in a WMA that is not part of a National Forest and there are no other more restrictive rules for that particular WMA, shoot it. All you have to do is step off the road and not shoot across the road. I see nothing in this that says you have to be any distance from a road. You just can't put up a blind within 50 yards of a road.
"constructs or places a hunting blind, stand, tower, or
platform within 50 yards of any designated road, marked unit
boundary, or designated campsite"

If it is a WMA that is part of a National Forest, do not shoot. The APH book goes on to state regarding APH units and WMAs within National Forest land, that the more restrictive rule will apply. I did not find the actual National Forest rules regarding this, but this is from the National Forest FAQ.
"How far off the road do you have to be to hunt?
You must be 150 yards off of roads, designated trails
and boundaries."

Disclaimer, Do ask your area controlling athority land manager or game warden. Mine is only an opinion from what published rules I could find.

OK. I am going to look into this further because this winter I plan on hunting in WMA's located within a Natl Forest. 150 yards seems extreme to me, especially if you park on a non-paved forest road, and hunt away from the road into the woods. Sniper John, you probably have a good answer for this question: What is the best way to measure out that you are 150 yds from a road in a WMA in a Natl Forest?
