The shooting grounds are located in the uninhabited wilderness along the Southern Oregon / Idaho border. It is about a twenty-minute drive from suburban Ontario, Oregon. Or, about forty minutes from the Boise Airport. Four-wheel drive is not necessary. You will be on gravel and some 'two rut' dirt roads. But they are all passable to conventional passenger cars.
The actual final campsite location may change slightly - but it will be on the same road in the same general area.
This is a map with most recent camp locations (we have used the current camp for the five years or more as it has easier access for campers).
Someone pointed out that the map above required a google sign-in to view it. I tried to fix it but just encase...here is a different link that shouldn't need to be signed in to view.
