I like that that map is very simple, uses the basic Google Map navigation tools and contains simple push pins used to drill down for more information.
I think that the site would benefit from custom pushpins to further add branding to the overall user experience.

I think that this points out a great strategy during development. Get your application out early listen to what your readers are saying and continue to evolve the overall experience. If the site flops then move on to something else.
