Your Question:
Will there be any RNC events(diners, etc) in the Park
Slope / Prospect Heights area that local liberals
could protest? Theres a lot here: the museum, the
library..

Answer: Here are two tours of Prospect Park/Park Slope
Brooklyn that New York & Company, the company
officially in charge of booking tours for the RNC, are
offering to RNC delegates, guests, etc. They are both
sold out.
