Hello and welcome!
I'm running the NYC Half-Marathon this March to raise money and awareness for the Wounded Warrior Project (http://www.woundedwarriorproject.org/). The WWP's mission is "To Honor and Empower Wounded Warriors" by supporting veterans injured in military service as well as their families. The range of services this 10-year old organization provides is impressive and meaningful and would not be possible without private support.
A picture is worth a thousand words so I encourage you to check out the WWP's 2012 Year In Review for an idea of the kind of programs your donation would make possible: http://www.youtube.com/watch?v=qa09iO0Dm9U
Lastly - the WWP is a 501(c)(3) organization (donations are 100% tax-deductible), and has been recognized as a Better Business Bureau Accredited Charity.
I hope that you will join me in supporting this worthy organization, and thank you for your support!
