food and drinks shouldnt run no more that $500, especially for 50-60 people (even a 100 people at $5 per person is more than enough). i think the biggest focus should be on getting the drag strip as early as possible. once that piece is situated, everything else is really minimal.
i know to rent Brian Piccolo Parks pavilion is about 150-200. it has a 3 foot grill, outlets...plenty parking and is not far from i95, i75, i595, or the t-pike. plus there are basketball courts, a skating park, a cycling ring, soccer/football fields, baseball/softball fields, playground, cricket
, volleyball...BPP has a lot of variety.
i can take care of getting the park if needed...i am always their and know the office admin as my cricket team is affiliated with the park.
another upside for BPP is that there are a few motels close by, plus malls...a couple clubs around the area too.
