When you realise how bright the moon is, turn your light off and you can see the trail/road in front. Riding your bike by moonlight, grin worthy.
Swimming in a lake, in the lake district in the middle of a hot day. Looking around at the mountains either side of the lake, getting the willys a little bit about what’s underneath you and is coming to chomp on your toe. Grab your goggles and duck down underwater near the bank, look up at the sunshine coming through the murky green. Swimming down with the little fishes to look for interesting pebbles.
