How can I promote my show Wayward Traveler to get more YouTube views?

I have a show called "Wayward Traveler Mini Docu: Nevada Train/Semi Collision 6.26.2011," that I just posted on YouTube. Without telling anyone about it we got 150 views in the first day. It's going up about 10 an hour at this point. Does anyone have any suggestions for how I can generate more YouTube views without sponsoring a YouTube channel or Facebook Marketing? I am more than well aware that posting it here will get me some views but I am really more interested in a legit way to get people to watch.
