OK.
1978, A car full of us, maybe 7. We pull WAAAAY out into a field, I mean WAAAY out, where there were just trails for bikes, no trees, just dried grass. The point was we had no where else to go to try out my new shipment of afghani. I fill the pipe, pass it around, pass it again and then in the distance we see headlights. Remember - 1978, a time where hash would put you in jail for time and a half. None of us actually believes the lights are those on a car that has left the highway but sure enough, they are coming toward us, and sure enough we can see the siloete of a police car. the car pulls right up in front of us, high beams, search light. The car stopps there for a moment, backs up a few feet and rolls right off the trail and goes around us and rumbles off. I am sure they saw 14 wide eyes in the car and have no idea what prompted the cop to continue on - horror.
I get stopped, I am under the influence of god knows what. The cop flashes his big flashlight on my right front tire "the tread is worn there, see? " "I look and as I do a medicine vial full of pot falls out of my top pocket, the cop points the light at the vial as I bend down and swipe it up, slipping it back in my pocket. "you ARE going to get new tires, right?" he asks, I say yes and go on my way.
I am pulled over, the cop asks for my driver's license and registration, as I open my glove compartment I see that I have forgotten the vacuum sealed oz of mushrooms stashed there. The cop sees it. "what are those" he asks, "oh, those are dried mushrooms, I make tea out of them". "never heard of that" he says, I show him my paperwork and am on my way.
A friend and I are stopped, the cop asks "is there pot in that vehicle sir?" My friend, who is driving says "I don't know". I think, now why the hell did you say that? "If you don't know, does that mean there might be sir?" "yes, it is my brother's car and I don't know what he does with his pot". So we sit as they strip the car and find nothing. We get home and tell his brother and he goes to the glove compartment, digs around and yanks a half an ounce out of a fake wd40 can.
I got lots of those kinds of stories but I don't know if they are horror stories or.... pre-horror stories.
