i have the "gift" where i can witch it and locate underground utilities. most people think it's hokus-pokus bullshit but it works every time, gas, water, electrical and drain lines - i can find them all. it's easy to get a general idea of where the utility should be based on where it comes into the house and where the service main line is and from there it's just a matter of a few minutes to find the line.
i recently mystified reductimat by finding the drain line under his basement concrete slab.
We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.
