This was done much more so than any others.
We bordered on a large plot of forest. So we'd pay attention if it was hunting season (wear orange/yellow if it was), and go traipsing through the forest. We would routinely be gone for hours. Some times, we'd go from sunrise to sunset.
We'd also build a tiny fire, and have cookouts. One of us had a rifle, so we'd go for small game. First time I had squirrel was doing that. We put out the fires like they told us to do in cub scouts.
(Tl;Dr. Kids with guns, fire, basic camping gear, out for hours)
There's no way in hell anything remotely like this would be "allowed" today.
