When is too many??
As I was thinking about this (Kind of like thinking about infinity, by the way. ) I started thinking about sink holes. So, logically, I am assuming that too many is when the weight of one's tools causes a sinkhole in the earth.
Of course, at the point where all your tools are in a sinkhole, it would be time to start again.
