Re: So, I've looked all over the Lorebook...
You can force a Google Map to return no more than a set max ceiling on results for a specific area. This is typically set at 50. As a person zooms in, 50 results are returned for whatever view a person is looking at -- at maximum zoom, all results for whatever area a person can see are displayed.
Anyway, I have no desire to wade through all like seven or so of the javascripts that you reference on the page to see which one's running your interactive Google Map and how you choose to code it, but the Google Maps API should provide you with the information that you need to implement a ceiling on results returned, if that's the route you want to use. You'd want to look at the GMarkerManager class.
As a level 1 burglar, Bilbo got a pony when he joined the Smaug The Dragon raid. Then he asked for leadership, looted the chest, assigned himself the 1st age Arkenstone and mailed it to an alt (Bilbo's a VIP so can mail from anywhere). They did some PvMP and an Epic Battle, then he apologized and gave the Arkenstone back because it wasn't BoA. He kept the pony.
