From the New York Times:
MIKE BARRETT does not have much of a yard at his two-story row house in Astoria, Queens. But that fact has not kept him from his new hobby of beekeeping — he put the hive on his roof. When it was harvest time this fall, he just tied ropes around each of the two honey-filled boxes in the hive, and lowered them to the ground.
Until last spring, Mr. Barrett would have been breaking the law and risking a $2,000 fine. But in March, New York City made beekeeping legal, and in so doing it joined a long list of other municipalities that have also lifted beekeeping bans in the last two years.
