haha.... so that nobody told and that small subway to park station which open just opposite to it on the other side of the road was missed on google map on my GPS. here in this picture I have shown the way (marked in green) that few guys out here are suggesting now and the way (marked in yellow) I took to reach PARK station. from the picture it is now evident that the subway is not exactly located outside MAS. One has to walk a bit to right to find the subway.
