Happy Hikers here,
My first impression is very negative. This is the sort of thing we stay away from, as well as grand kids .
While I applaud the fact you disabled the mechanism, it still just dosen't belong here. It is something that can cause extreme physical harm in it's working state. Aside from this, should someone else come accross this, can you imagine the negative press it could get?
There are numerous ideas to bring about a scary cache without the negative impression of this one. Let the imagination roll.....
