leave them alone, just walk around them.
all of the other posts have excellent information.
especially when it comes to inquisitive children, this nails it.
you are in their home, they don't want you - you're too big, leave them alone, and go around them if at all possible.
a poster above said to watch for 'cow pies'. could be a coiled snake. typically seen this way.
and i have also seen them stretched straight out from the roadside like a stick.
keep your eyes open. and have the kids leave them alone.
