I'm aware that most of uncle sam's material are in the public domain, where are some of the places I can find them? How do I know for sure that I can use them freely. Don't tell me to go to gutenberg or to buy some out of print books because my topic didn't exist before the 1920s. Where's a good place to get public domain material from uncle sam which have newer topics?
I use their content all of the time for my road rage site. Search for NHTSA. After reading a ton of articles, and stats... Not paying attention is the #1 to get into an accident. Driving drunk is a good way to kill someone. Speeding is a better indicator of driving drunk than weaving. You are a crazy if you don't wear your seatbelt going just 1 mile.
