Bunny - this name conjured up memories of skiing my local ski hill in Minnesota as a young child and that cute girl at the same hill as a teenager. Those Bunnies and this one are not the same.
Bunny is a horse trail. It would be great if it were cleaned up for MTBing, but it's not. It's loose dirt & rock with some great steps along the way. It's not a bad way up just quite loose from the countless hooves that travel this path. If you choose this path up the mountain I recommend Fossil Canyon
for the remainder of the journey up.
