On April 21, in an undisclosed year in the 20th Century, I turned 21. My roommates threw a big shindig for me, which they cleverly called the Bearthday Party, combining the festivities of a milestone birthday with the commemoration of Earth Day, April 22. We were a clan of new bohemians who did things that weren't as common back then as they are now, like composting and recycling; tree hugging and rainbow gazing. So, this holiday was right in line with our lifestyle and a good reason to celebrate for 48 hours straight.
