Find Nearby Place

So... if you are given a latitude and a longitude values and you want to find a nearby place, then you have to check out GeoNames. They have a web API that you can access for free (as in beer :-) Here is a simple usage of the API using the Flex API for AGS:

                httpService.send( urlVar );
