Even on a private property, accidents happen. I would know, the ONE day I hunted without hunter orange(in TX so not against the law), my dad and I got separated and he accidentally shot me through the thigh. I was lucky as the bullet travelled at an angle through 10" of flesh without hitting bone, artery, or tendons. Granted, it passed within less than 1/4" of each of these... Hunter orange is and absolute must! If a veteran hunter of 35 years experience can make a mistake, anyone can.
