I have all-you-can-carry, absolutely free, rainwater and mud. Must bring your own containers. Water is sitting on open fields, in ditches, and running over banks of nearby river. Mud is easy to find..just look wherever water used to be. I would advise bringing water-proof, knee-high boots along to wear. This is no joke..all the water you want is free as long as you have a way to haul it to your place!!!! I will even stand in the doorway of my home and wave as you take it away!
