@notSoJunkDNA Sigh…yes, very frustrating. But there is always the Tram which is a fun and scenic mode of transport!

Without the Queens bound F train service to Roosevelt Island this weekend, the Manhattan Tram station was packed with people. Here is what it was like waiting on the Manhattan Tram Platform at about 5 PM even after a fully occupied Tram just left the station. 
As the people on the station boarded the Tram and left for the Roosevelt Island side, ofthers were left waiting 
for the next Tram. I was told the crowds were like this for most of the day. The Roosevelt Island Twitterverse asked:
@ClassyMalick tourists, Zog ball players and no f train service from Manhattan this weekend cause the overcrowding
