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.
Last time I heard an artist quote a sleeve, his price was $2,000 for the entire arm or $1,000 for shoulder to elbow (half sleeve.) Here's the thing though: Every artist will vary, there is no 'standard going rate' and you get what you pay for. Some artists charge by the hour and you pay for however long it takes to get work done.
