If you haven't strolled along the springy walkways that make Big Bambu such a thrill to visit, you have just 20 days remaining to do that. Mike and Doug Starn's installation on the roof of the Metropolitan Museum of Art closes after Halloween. The views of the Manhattan skyline are extraordinary, and Big Bambu - a multi-dimensional work of art that offers visitors an experience of art and philosophy on a continuum, as the piece grows, expands, and changes from day to day - is a must.

As the closing date nears crowds are likely to expand, so here are some strategies for getting in. If you arrive a bit before opening, say 9:20 am, you stand an excellent chance of being at the front of the line. Doors open to the public at 9:30 for the first tour of the day, and weekdays are less crowded than weekends. It's important to read the Museum webpage about tour hours and restrictions. For example, children must be at least 10 years old; your cameras and cell phones will be placed in a locker; you must wear closed, sneaker-like shoes; etc. Guided tours of Big Bambu are free with museum admission.

Big Bambu continues through October 31, 2010. Metropolitan Museum of Art. 1000 Fifth Avenue - enter at the Uris Center, at ground level opposite 81st Street - NY, NY. Read Mike Starn's exclusive interview with DART, posted last July .
