Scraping a locator map?

[Sylvester Graham]

Hey guys/girls, 

I'm trying to gather names off a "dealer locator map," you know, the kind where you put in your zip and then a map appears with a list of people/companies within a specified radius. 

Does anyone have any experience scraping these types of sites? The site I am on, according to source code, currently uses "gmaps" which I assume to be google maps app. 

Thanks, 

Sylv
