The Regional Balls will set you back $150 if you get an invitation. Here's the lineup:
Eastern (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont, Puerto Rico and the U.S. Virgin Islands); Mid-Atlantic (Maryland, Virginia, the District of Columbia, New York, New Jersey and West Virginia); Southern (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee and Texas); Midwest (Kansas, Indiana, Iowa, Michigan, Minnesota, North Dakota, South Dakota, Nebraska, Ohio, Wisconsin and Missouri); Western (Alaska, California, Idaho, Montana, Oregon, Washington, Wyoming, Arizona, Colorado, Nevada, New Mexico, Utah, Oklahoma and Guam)
Of course, the official balls will not be the only parties in Washington the night of inauguration. Several companies, states and organizations will hold events throughout the city. And if you want to go to a bar and raise a glass in celebration of the new administration, the District of Columbia will let you do that into the wee hours of the morning. The D.C. council will allow bars to serve until 4 a.m. It had originally agreed to let the drinking establishments stay open until 5 a.m. but some congressional leaders thought that would put a strain on police.
Bottom line, there won't be a shortage of places for those who want to party.
