Your Advice for DC's Roosevelt Island ?

In an article posted yesterday on DC Metrocentric, writer Chris Loos posted the question whether their Roosevelt Island, currently federal park land, should be developed for residential housing? I am curious what readers of this blog have to offer as advice?

My personal opinion is that they should not give up the park space as it now stands. The pictures I have seen on Flickr show it to be a rare treasure in a City where most open land has XYZ national monuments etc. Except for the Teddy Roosevelt monument my understanding the space is baically untouched and accessible to the public.

Roosevelt Island for Sale - Part 2

Apparently there is a blog related to the Private Islands Online real estate website offering that Montana Roosevelt Island for sale. The blog Islomania is restating the "history" that the Island was bought by Teddy Roosevelt's great great grandfather Frederick.

The problem is that according to Genealogy.com I see no great great grandfather for Teddy named Frederick. Also the years don’t seem correct if Teddy was born in 1858. This fact was pointed out to me in the comments to my earlier "For Sale" post. I think Private Islands Online needs to check their history if their are using such info to sell that island and I sent them an e-mail pointing out the discrepancy.
