Heh...you joke, but there were farmers back home that seriesly believed in ghost cows. I'm not kiddin'!
There was a family who kept younger heifers in a barn near our house - the main barn was a few miles away. Every so often the heifers would get out (usually every couple years there was an extra smart one that'd lead the others into trouble) and we'd have to call the farmer to let him know they were wandering where they shouldn't be.
One time we just saw one out - strangely it appeared to be a milk cow rather than a heifer - and called about her. Talked to the farmer's wife, but she just said "Oh, that's so-and-so...she passed away a few years ago, but she shows up now and then." Um...kay.
Heh!!
Oh my...
