I first read this piece by Garrison Keillor in the late 1990's and (not surprisingly) I've been thinking about it lately.
From the Prairie Home Companion website: "On July 4, 1998, Garrison Keillor was on the cover of Newsweek magazine. The edition featured a three-page essay by Keillor called 'Laying on Our Backs Looking Up at the Stars.' In it he talks about the United States, the Revolution, the Declaration of Independence, and the country's immigrants." This is the end of that essay.
