About National Underground America Day
May 14th is Underground America Day, a time to honor the 6,000 or so North Americans who make their homes not only on the Earth but in it. Underground America Day began in 1974, when architect Malcolm Wells came up with the idea.
"I woke up one day to the fact that the Earth's surface was made for living plants, not industrial plants."
"On May 14th each year hundreds of millions of people all across this great land will do absolutely nothing about the national holiday I declared in 1974, and that's just the way it should be.
"It's a holiday free of holiday obligations.
"You don't even have to lose a day of work. But if you're the partying type, here are some of the ways in which you can observe the big day."
