my laptop went back to the repair shop again on monday, and finally got it back today. nothing serious this time but just a bit of tweaking. hopefully i wouldn't get any more virus attack on my laptop. anyway, went to check out the city's new attraction in chelsea with my students. basically, its an old elevated rail line that was turned into public park which stretches around 8 blocks from 23rd street in chelsea to gansevoort street in the meatpacking district. it was officially opened just last week.
