Orange is best.
It's the accepted color for hunters.
The more the better.
My suggestion is cover the highest points (head and top of pack).
Another thing to keep in mind is for all you folks who like to hike in spring.
In many places (especially here in PA) it's one of the most dangerous hunting seasons.
Spring Gobbler is full camo and no stalking.
Pretty much it means that if something is moving, it's not a hunter because they can only hunt stationary.
Now, in a perfect world, no one would ever pull a trigger with a 100% ID of what they are shooting and everything behind it.
We know that doesn't always happen.
There are the few who shoot first and ask questions later.
These are by farthe exception, but they're out there.
So, make noise, wear orange, and be careful.
Oh, and please be respectful.
As a hunter I can tell you 99% of us are happy to share the woods and know not to hunt close to trails if we don't want to be disturbed.
But there are always the "ones" who just don't get it.
Best to walk away.
Whether you're hiking or hunting, BE SAFE.
See you the trail or in the woods.
