I used to deliver the Vancouver Province up the side of a mountain (Johnson St.) in the mornings. Not many people lived up there than, I had 17 or so customers but I got a $10 mileage bonus because of it's remoteness. I'd mostly push my bike  up the hill with my three dogs and ride down. Built up strong legs doing that for a few years. One morning I decided to take my sister's horse Rocky (half gilding). He wasn't anymore pleased to be up in the morning as I was and he attacked me (ears down, teeth bared)  and than spun kicking me in the stomach, throwing me about 10' or 15'. I was close enough that I was more pushed than kicked, so I survived fine but it was the last time I tried to use him on my paper route although we became pretty good buddies and I rode him often later.  Well maybe not buddies but I learned how to fool him by shaking a can filled with pebbles so he'd think I had oats for him, so I could grab him. 
Now the area is all built up and the road is paved.
