Here are some really wierd findings for searching on Google Local and/or the insertion of a onebox into organic searches.
I guess Google hates advertising Agencies:
I'm not going to do screen shots on all of them but take a look at the onebox inserts for these searches: --Washington DC
The one box includes 3 hotels. Take a look at the longer list of "advertising agencies" and you'll find more hotels, The Kennedy Center (for performing arts), a museum, a a law firm.
One box results--2 Universities plus a law firm and get into the depth of listings and it includes hospitals, a museum, etc.
Baltimore Natl Aquarium, Walters Art Museum, University of Baltimore....and go deeper and you'll find more Universities and the website for the Maryland Transit Authority....among others.
I know there is a debate about whether SEO should be performed by advertising agencies or SEO's.....but geez....I think the agencies should correct this wierd phenomena before they start trying to get web business!!
