Second Life events are ideal for iCalendar / hCalendar because their
locations tend to be simple spots on a grid within SL ("IslandName
(129,104)" for example), and such text strings fit well into a
"Location:" field.
But real-world public events at venues you may have never heard of
tend not to fare so well, as the world isn't very careful about how it
populates "Location:" fields when describing a venue (that has a name,
a street address, a city, a state or province, a country, a lat/long,
a phone number, a URL, a photo, etc.)
