Not such an easy answer for this one because I can't say that any one person is my hero really. I can say there were people who influenced my life in great ways, but I don't think that qualifies for heroism. No, I think the true heroes are people who do selfless acts for the good of others. Firefighters, police officers, and those serving the military would be at the absolute top of my list. To tie this in with Deltaville, I'd have to say that all the volunteers who helped during the tornado cleanup, feeding people, clearing debris, searching for anyone trapped, searching for bodies (of which there were, thankfully, none)- those who basically saw help was needed and helped- those people are heroes.
So thank you to anyone willing to lend a helping hand, willing to put their life on the line to save another.
