Snare constructed by Eric Quesnelle.
A Pencil Snare consists of two sticks pushed vertically
into the ground. A stub on each stick facing inward holds the
trigger stick in place. A spring stick of some sort is above the
whole snare - in this case, the white string leads up to it.
The rounded aspect of the sticks helps to make this
snare sensitive, allowing the trigger stick to roll out from under
