Actually some of the best track media is on NYC. Many don't know but the best writers and master minds of the sport are here.
The stadium on Randall's Island is capable of be expanded to hold 20K either portable seating or structual. The city would work with the MTA to develope transportation for an event of that size and has worked well. The concerts that are on the island have had over 40,000 people and getting there and off is not bad.
Everyone says Eugene is track city USA but why. Because of the legend that exisit's in "Pre"? NYC probably has more large running/track and field events then anywhere else in the United States. How many events does Eugene host year round that attracts more then 3000 people with spectators and athletes. NYC off the top of my head I would have to say at least 25 that I know of and wouldn't be surprised if the real number is more like 35 or 40.
I do agree that NYC needs help with marketing and getting the fans out there. I bet NYC has more track and field fans then Eugene but in Eugene track and field is huge. What else is there to do in Eugene on a Saturday night? In NYC many things get lost and I run into people all the time and say why did I see you at the Armory, Icahn, VCP...usually the answer is "I didn't know about it". Hopefully with USATF setting up offices in NYC will help greatly in increasing the participation rates and the help bring the track and field events to the events. Don'tbe surprised if Reebok this year see's 10,000+ spectators.
I think NYC will take very large steps in the next 5-10 years and really do some see many impressive changes and events come to town.
