The feed URL should be a publicly accessible URL containing data corresponding to the spec below. If you have over 200 articles worth of content, we strongly recommend that you support the offset and limit URL query parameters. offset=0 refers to the most recently published article and higher offset values refer to older articles. The limit parameter specifies the number of articles to return. For example, http://example.com/feed?offset=0&limit=50 would return the 50 most recent articles. If the offset parameter is not specified, then assume a default value of offset=0. If the limit parameter is not specified, then assume a default value of limit=50.

<!-- The feed format is standard RSS with Field Trip-specific extensions. It must be well-formed XML. You can check this using the W3C Validator (http://validator.w3.org/).

Note that tag names are case-sensitive. Consider enclosing tag content in a <![CDATA[ ]]> tag if XML special characters may appear in the content. Otherwise, you must escape special characters with their corresponding entity references (http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Predefined_entities_in_XML).

All text in the feed must be encoded as UTF-8. -->

<description><![CDATA[<p>Located in San Francisco, the Golden Gate Bridge is actually orange. And very large. It was build quite some time ago, and is a major tourist attraction.</p>

<p>The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, the structure links the city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County. It is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the modern Wonders of the World by the American Society of Civil Engineers. The Frommers travel guide considers the Golden Gate Bridge "possibly the most beautiful, certainly the most photographed, bridge in the world."</p>

<p>While the purpose of the structure also remains unknown, some of the designs suggest associations with India and Egypt. Within the mosaics, visitors can find repeated designs of skeletons, crocodiles, owls, turtles, trees of life phalluses, gods, goddesses, and what appears to be an altar, but interpretations of this remain subjective. Since the Grotto opened to the public in 1937, experts have hypothesized its purpose from everything to an ancient temple to a meeting place of a secret pagan group. The most recent findings point to the Grotto functioning as a sun temple, the sun entering the Dome (which extends up to ground level, with a small circular opening) just before the Spring Equinox, forming a dramatic alignment at midday on the Summer Solstice and departing just after the Autumn Equinox, thus indicating the fertile season. But still, no one can be sure.</p>]]></description>

<!-- REQUIRED, except in special cases (see below): One of either <georss:point> or <fieldtrip:address> must be specified. <georss:point> specifies a latitude and longitude. <fieldtrip:address> must be a full unambiguous address which corresponds to a specific location. You can check this using Google Maps (https://maps.google.com/). If both <georss:point> and <fieldtrip:address> are provided, <georss:point> will take precedence. Items without at least one of these tags won’t be shown in Field Trip.

Items that don’t have any location-relevant content should either be omitted from the feed altogether or as a special case have their <georss:point> and <fieldtrip:address> tags omitted.
