NORTHWEST -- Perched far above the city, with sweeping views of both the Washington Monument and the White House, animal lovers happily howled at the moon on Friday evening, during the
W Washington, DC�s annual Halloween-themed celebration.
Bats greeted guests on the hotel�s doorsteps�
This year�s sold-out party, dubbed the �Howl-O-Ween Bash�, was co-sponsored by beverage giant
Bacardi, with a portion of the proceeds benefiting the
Fashion for Paws program of the
Washington Humane Society.

A waiting list that spanned more than 400 names proved the popularity of one of D.C.�s most coveted late night destinations, as guests were invited to sample from
P.O.V�s award-winning cocktail menu while grooving to the beats spun by a live DJ.

A series of specially-priced brews, including a �Bubbling Boo Brew� (Bacardi Superior Rum, Cola), �Bat Bite� (Bacardi Superior Rum, Rasberry Liqueur, Cranberry Juice), and �Bacardi Zombie� (Bacardi Superior Rum, Bacardi Gold Rum, Grenadine, Triple Sec, Sweet and Sour Mix, Orange Juice), had been crafted just for the occasion and attendees eagerly indulged.

Given the hotel�s proximity to the White House, politicos, media stars, and journalists were among the evening�s many supporters, including a quick stop by the current administration�s Assistant to the President and Director of Speechwriting,
Jon Favreau.
President Obama's Director of Speechwriting, Jon Favreau, and W Washington, D.C. Marketing Manager Kaitlyn Ferrara.
And while Favreau�s costume as one of the members of the hitmaking electro pop group
LMFAO (well, as best we can tell at least) was clearly well thought-out, it was Potomac�s
Yousuf Hanif who took home the night�s �Best Costume� prize for his portrayal of a young Andre Agassi.
The debt ceiling. Ah, D.C. costumes�
All told, this year�s Howl-O-Ween Bash raised more than $5,000 for Fashion for Paws. Truly fearful fundraising!
