INFORMATION ABOUT BALTIMORE:


   Baltimore has undergone a tremendous revitalization in recent
years. Baltimore's new showplace is the Inner Harbor area, where you
will find boutiques and cafes, as well as the National Aquarium,
Maryland Science Center, and the Pier 6 Concert Pavilion. Throughout
the summer the city sponsors Ethnic Festivals of every description,
culminating in a grand City Fair. Its historic sites include Fort
McHenry, the Edgar Allen Poe House, and the first frigate of the U.S.
Navy, the U.S.F. Constellation. The Baltimore Museum of Art, adjacent
to the Homewood campus of The Johns Hopkins University, and the
Walters Art Gallery, both house excellent permanent collections and
attract important traveling exhibitions. Other cultural facilities and
attractions include the Baltimore Symphony Orchestra, Center Stage,
the Lyric Opera House, Meyerhoff Symphony Hall, Morris A. Mechanic
Theatre, and Peabody Institute. Baltimore also is only an hour north of
Washington, D.C. and its treasure trove of monuments, museums,
libraries, parks, and theaters. In mid May the temperature range is
typically between 52 (11C) and 74 (23C) degrees. The relative
humidity is about 53 and there is 56% chance of sunshine.
