I'm fairly sure my horses prefer mud puddles
because they are warmer than the streams, rivers, lakes & troughs in the
winter & spring. And, sometimes their placement on the trail, like
at the top of a long climb, makes them more enticing than the water trough or
creek 2 miles ahead. Maybe if I were an expert on horse communication, I
could figure out if the horses think there is so little water
available (only a puddle!) that they'd better drink it now before there's none
left for them. Hmmm, maybe that's it!
