The University of Maryland at Baltimore is closing April 6, the Orioles' Opening day at Oriole Park at Camden Yards, giving a holiday to 4,000 students and faculty members at the downtown campus. The UMAB administration cited the parking and traffic "nightmare" expected downtown and a desire to be "good neighbors" to the new stadium. Classes will have to be made up.

The Evening Sun would like to know what you think. Should the college campus be closed because of a baseball game? Do you think the traffic and parking problems will be so bad that this is necessary?
