The ease of access to Rabbit Lake probably contributed to the lack of a knife among the four of us. It's 4 1/2 miles or so of relatively flat trail that, especially on a sunny Saturday, is very popular and well traveled. Close enough to the city to where you wouldn't really think of needing to build a fire if you're just out for a couple of hours. Granted, I always carry a knife/multitool now on every hike. But on that day, none of us had one.
