I see many nice rounded pebbles in the ZEN garden, great for kindness rocks hahaha. Just kidding, I would just enjoy the moment there and wouldn't pick any rocks, although I do have some rocks picked for me and brought to me from your continent 😉
Mrs Bozz did a great job with the photos. When we go on a trip, it is usually my husband who drives and sometimes he tells me to take a few photos when we see something interesting, but I don't do it... as my photos from the car are always bad, so I just enjoy the views without even trying to take any pictures.
