I never used to carry when I rode, but I've had several instances where I've felt there was/could of had been a need. Twice I've run into dogs in the woods where I thought they were going to come at me. One I was able to get away from and one was called off from his master once he came into view of the situation. Another time I ran into a homeless man, or should I say I accidentally ran into his makeshift camp. His reaction left me very happy I was moving pretty quick at the time. The last instance convinced me it was time. I was riding on the road by myself and all the way over as far as I could when a guy thought he'd mess with me and was screaming at me as he edged his car closer and closer to me. It happened fast enough that I couldn't stop before I had to put my hand on his car because he got that close, which really sent the guy into a rage. I ended up on someone's lawn with the guy stopped and screaming at me, shaking his fist all the time yelling I shouldn't be on the road and he should of run me over. Blah blah blah. After that, I started carrying all the time when I ride.
