My son Justin (he's 9) comes up to me just now saying, "Dad I have a question". Oh crap I'm thinking, it's to early to be fielding sex or other major topics..... "Dad, if you fire a gun in space what will happen?" Ohhh thank god..... "Well, guess it will just travel till it hits something, or just keep going." I'm just guessing here. I thought it was a pretty cool question from my 9 y/o. THAT'S MY BOY!!!!!!
