It was terribly wet everywhere on the D of E practice expedition but especially on the bog before High Seat. I resorted to putting my foot down gently so as not to sink in. This is because the slower my foot is going, the less momentum it has when it hits the ground. That means it has less momentum to lose in a given time, so the rate of change of momentum will be smaller, which means that the impact force is smaller and I don't sink in as easily.
