问题
I've been digging around on the Facebook developer site to see if there is a way to get local event information for display on my own web app.
Ideally, I would pass up a location and Facebook would send down a list of local public events (with links to FB of course). But as yet I haven't found any documentation which says whether this is possible.
Does anyone know if this is possible?

It is possible indeed to receive events using location based "search" To do so you'll need the longitude and latitude coordinates of the location you want to search and a access_token with user_events permission (i think you could also use the public search)
Here's an FQL example how can you get all the events nearby of a location. (this searches from your and your friends events):
$lat = "40";
$long = "30";
// using offset gives us a "square" on the map from where to search the events
$offset = 0.4;
$events = 'SELECT pic_big, name, venue, location, start_time, eid FROM event WHERE eid IN (SELECT eid FROM event_member WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me()) AND start_time > '. $created_time .' OR uid = me()) AND start_time > '. $created_time .' AND venue.longitude < \''. ($long+$offset) .'\' AND venue.latitude < \''. ($lat+$offset) .'\' AND venue.longitude > \''. ($long-$offset) .'\' AND venue.latitude > \''. ($lat-$offset) .'\' ORDER BY start_time ASC '. $limit;
The trick itself lies in the venue.longitude and venue.latitude useage. To get events from a city, just get the city coordinates and adjust the offset to your needs. If you don't know how to use FQL please look into Facebook PHP SDK

the quotes around the lat/longitude makes them a string. You'd be then comparing a float to a string
