Hitchhiker’s Heaven
Hippies were a big deal during the ’70s; people were generally very enthusiastic about the movement and exercised love and brotherhood to help further the cause. Some people chose to risk it and tried hitching a ride. It isn’t new; it’s how they used to travel, limiting their carbon footprint.
Woodstock itself was around 100 miles off New York. So when people without transport needed a ride to get there, it was pretty clear that it wasn’t some isolated issue. There were huge crowds of hitchhikers, people were willing to ride on any vehicle in any way to get there. Several strangers became friends with each other after it.
