Road trip tent camping anyone?

Decades ago a bunch of us were going up to Lethbridge for a big Jeep event, and arrived at the port in MT (I don't remember which one) late, 11? at night or something. We didn't even make camp just threw down the bags and ground cloth and crawled in. I probably would not do that nowadays LOL
Did that back in about 197? something. In Idaho at I think it was a reservoir Lake Palisades ?
jumped off the road me and my brother and threw our sleeping bags on the ground and figured a good place to fish in the morning. About 5 am heard a bunch of sheep bleating and looked up and yep about 500 sheep being herded heading or way. Never moved so fast getting camp back in the car and was funny all the guys herding the sheep on there horses were laughing so hard thought they might fall off.
