How are distances calculated from a city selected in the activities search pull down menu to the destination sites that come up in the search results page?
Distances are an approximation based on the zip code of the destination site and the zip code of the city selected in the pull down menu. Don’t think for a minute that these distances are anything other than a general estimate of the actual distance you will need to travel. We decided to use zip codes because many of the destination sites on our website do not have physical addresses and 2010 is far to early to be able to get GPS coordinates easily for all of our destination sites. If you want more accurate information for the destinations that have a physical address, you will have to use Mapquest or some similar service. In any event, by designing the system to express distances based on zip codes you will be able to filter your search results even though the actual distances between the departure point and the destination point will not be entirely accurate.
