I've seen a ton of great ideas in my stream in the last hour or two that range from donating your hotel room to Sandy refugees to spending the weekend on the LES walking stairs (How many stairs = a marathon?) to deliver food/water to the elderly.
Ask to join if you have solid suggestions for how Marathoners stranded in NYC can help with Sandy relief AND links, contact information, or resources so people who see this can follow up.
Thanks! Stay safe, everyone.
