Can I ask what year that was in? Several people in here seem to be intimately familiar with this company, but it's my first time hearing about it, despite me being quite interested in travel and all sorts of weird transit methods. It made me wonder if everyone here used them when they were at their peak many decades ago, or if this varied.
1997 for me.
1989. I saw a paper flyer in the New York Public Library and turned up a few days later at the bus station on impulse. It was basically a moving commune, where you slept on flat boards, cooked together and moved glacially slowly towards the destination. The NY -> SF went south via FL, TX etc. It was mainly young people not actually from the US, Europe, Australia etc.
