Welcome Darin,
Your perception of the addictive qualities of the hobby is correct.
As you're reading this, there are groups of less assertive employers, spouses, family members, and even clergy, meeting to draft a multiple step therapy program to help us poor unfortunate souls rehabilitate our lives. I really doubt that these efforts will have any significant effect.
Unfortunately, some municipalities and one state, if my information is correct, have enacted statutes prohibiting detecting on specified and general public lands. "Ouch!"
I doubt that even a new amendment to the constitution will be able to completely eradicate the results of the uncontrollable desire of the majority of us. Were such an amendment to become law, we would only take our activities deeper underground, a goal toward which we're already diligently striving.
Our obsessive compulsive needs to get into our detecting clothes, travel various distances, sweep our motley instruments, kneel on terrain from sand to tundra, dig holes in mud and asphalt, and get dirt under our fingernails, all to find the elusive items of urban and rural archaeology, are rapidly evolving into the most basic survival instincts known to humanity.
Welcome to the resurgence of the way of our ancestors, the hunter gatherer society.
Respectfully,
The Nutty Teacher
