When I went to school there, there were lots of things that would have the "same effect."
If you were a liberal loon, a whiff of the aroma of pot, someone willing to share a bottle of cheap wine, or the blood bank offering an extra $5 for plasma were all just as good.
On the other hand, some good barbecue coupled with a six pack of Lone Star long necks was an easy way to send us conservatives into orbit.
I lived there in 1973. You are dead-on!
