This is a good tip. They have to be getting water somewhere, I have seen deer drinking from tiny seeps that hardly anyone would know about.LOL! Always someone willing to piss in the cornflakes! Even if it would benefit a ton of animals.
The guys who demand that everyone always take the hard way - maybe they should tie their shoe laces together and hunt that way - it'll make it more challenging for you.
Water is a big thing - OP could always find and open up a seep.
No livestock. Arid southwest.Are there any livestock in the area? If so they will drink all your hard work.
Do something smaller that will have less evaporative loss. A small stock trough from a farm store. Or a 5 gallon bucket.
Interesting project. Keeps us updated.
