 Park officials have been skeptical of the claim that hundreds of thousands of people could fit in the Great Lawn, since Bon Jovi's concert in 2008 which filled the lawn.Only about of the lawn are estimated to be usable during concerts, and about 6,000 to 8,000 people could fit in an average acre if each person had of personal space.During the 2004 Republican National Convention, NYC Parks denied protesters the right to organize in either the Great Lawn or North Meadow, citing concerns over possible damage to the turf.
