PL, Ben,
I have seen many bullets in flight. However, all were on the same target range, and IIRC, all were in the later afternoon. I was always the shooter. Most were .22 LR fired from a rifle, and one was a .38 Sp. WC. I think lighting conditions are the main determinant. Probably minimum velocity, recoil, and smoke also help a lot.
As to your views especially re guns, I wholeheartedly agree. Indeed, one remarkably pleasing feature of this non-shooting website is the general favor with which guns are seen here. It makes for a very pleasant atmosphere (as well as realistic approach in living). You know you are in good company when the really spirited but still civil discussions revolve around which guns and which knives to choose for survival, business, and recreational purposes. <img src="images/graemlins/smile.gif" alt="" />
