The recent wintery weather means that salt levels are at an all time low due to the constant gritting of this nations roads. What this means is that for anyone who wishes to hide in a GRIT BIN this is a golden age of opportunity. However one must still be cautious of being in a GRIT BIN when it is being refilled with precious salt or being emptied of it's salty cargo.
