Roosevelt Island Volunteering on Christmas Day

A reader sends in this question seeking places to volunteer on Christmas Day. Any ideas?

Do you know of any Christmas Day volunteering opportunities on Roosevelt Island, perhaps at the senior center? Any info you could give (including pointing me in the direction of others who may know) would be wonderful.

Here is a link to Roosevelt Island charities from Charity Guide that may be of help.
