Someone was saying blueline buses will be top plying from 20th Sep and blue lane challen or 100% effect would also start from 20th Sep. So people would like to travel by Metro only and then it would not be very pleasent situation. Even now a days metro is full and people seldom find place to sit or stand peacefully.
Moreover, after CWG or a month probability of few more members from Delhi / NCR joining in are more rather then today or 5 days from now (just an example). Rest is your choice.
