I wouldn't worry about it. If you are unlucky enough to get shot by a random bullet, it's likely the shot came from so far away that the shooter couldn't have seen your red Krill light with a 50 inch scope. <img src="/images/graemlins/smile.gif" alt="" />

There was a case some decades ago in New York where some poor idiot was taking pot shots at tin cans floating in the water, without realising that the bullets were skipping off the water and sailing over the ridge. He managed to hit an unlucky university student who was driving down the freeway, over a mile away, in the back of the head, killing her.

Poachers (or hunters) shooting at something moving just because they see movement is a far greater concern to me, but not likely to happen while I'm sleeping, even in my Hennessy hammock.
