Plane tickets aren't that much... there's houses available for free for people there... so if you need help with the plane ticket, and are good at volunteering for this... I am SURE a few of us could help you out...
I'm donating to Operation Live Free or Die today, so my hope is anyone willing to go canvas in NH can get funds/assistance through them. My wife and I are also writing letters to Iowa - basically doing what we can to help in these states (we're in Texas).
Please do report back let us know if OLFD can help you.
BTW: Love the enthusiasm of canvasing "like a rock star"! Keep the enthusiasm up!
