Uptown has long struggled with poor management of Parks concessions. Illegal vendors roam many parks without enforcement. Large concessions like La Marina blatantly ignore entire pages of their contracts under the protection of political influence (see http://dyckmanmarina.wordpress.com/ for more). Parks needs to treat uptown like it would other parts of Manhattan. Having more concessions is great -- it adds services to the parks and brings in revenue for the city -- but it must be managed properly.
