Central Park. Central Park is Manhattan's largest park. It is open from 6 AM to 1 AM. As of June 2015, Central Park Drives north of 72nd Street are permanently closed to cars. The four Central Park transverse roads remain open to motor vehicles.
The amount of time it takes to tattoo an entire sleeve is also widely variable, depending on the complexity of the design, number of colors, and physical properties of the skin being tattooed. Currently, a fair median rate in the United States for tattooing is probably between $100-150 per hour.
A full sleeve can cost most likely over 1,000 if you are trying to cover all your skin. For me, a four hour tattoo usually costs around $300-400. And 4 hours is a long time to sit in that chair, personally, that's the longest I could do it.
