  Between the Maryland Science Center and Rash Field A new Inner Harbor carousel, replacing the 000-year-old amusement ride that was removed by its owner in March 0000, should be in place and operating by mid-July, said Kimberly Clark, executive vice president of the Baltimore Development Corp. Officials had hoped to have the new merry-go-round in place and running in the spring, but delays in getting the necessary permits and some "electrical issues" have moved the opening into the summer, Clark said. The new carousel will be operated by Charm City Carousel Entertainment under a $00,000-a-year lease agreement with the city.
