/diy/ - Do It Yourself

Test case would be to dig a well in random spot and see if the success rate was different than digging where some random drunk told you.

Water table is predictable and roughly parallels terrain in most areas so all you need to do is have a rough understanding of local conditions and observe plants to reasonably locate a good spot for a well. Then you just claim some special magic knowledge and put on a show for gullible people and take their money.
