From last thread:

re: #177 Teddy’s Person

When I lived in DC and worked for the government, carpooling was huge. I don’t know how the system got set up. There were places in the burbs where you could pick up a carpool and specific places in DC where these carpools got dropped off. Most people carpooled in organized carpools. If you missed your carpool or is wasn’t running on a specific day, you could go to a designated pick up spot and get a ride into DC.

I remember talking to a co-worker who carpooled from VA south of DC. Her carpool wasn’t running one day so she went to the Springfield Mall and found a carpool that needed a rider who would drop off near our office.

This was all well organized in the early-mid 1990s. I suspect they use existing social media these days.
