Hi! This is a very nice and refreshing post. The young cow must be very happy to greet you. She must be quite a hiker, it seems she is on a hill or mountain with a big boulder.
The graffiti must have been done by some tourists after consuming one of those 'magic' mushroom! Your discovery may give rise to a home grown local family industry!!
From you post, you are having such a good life in fantastic surroundings which makes us city dwellers green with envy!

Best wishes for the good life!
Cheers.
