I visited Pony Penning during the summer of 1988 while serving as a seasonal park ranger at Assateague Island National Seashore. The following year, this article appeared in Cappers, a weekly tabloid newspaper published in Topeka, Kansas, with national distribution. Cappers began as Cappers Weekly early in the 20th century, has changed names over the years, and is now published as Cappers Farmer.
