Snow in Summer

Have you ever had a snowball fight in the summer?
It sounds like a conundrum, doesn't it? After all, summer, by definition, is warm if not not.
But eight years ago, my family took the picture above. In June. In Colorado.
The story behind it? My mom's family went to Colorado several times while she was growing up. They'd find snow on the side of the road, stop, and have a snowball fight. And they'd take a picture a lot like the one above.
But the one above is me, my sister, my brother, and my brother-in-law (and niece). Posing to be like our mom.
Let me tell you. Snow in summer isn't nice snow. It's hard and crunchy and hurts a bit if you throw it. But it's also irresistible because how often do you find it when you're hot and sweaty?
Up in the mountains, it's just high enough elevation, that if the shade is just right, that snow can stay awhile. In my latest book, Operation Find a Guy, Skye and Benjamin stumble across a small patch of snow during a hike. I couldn't resist. It was the perfect way to lighten the scene I was in. And lead into the next one. ;)
I did take a bit of a liberty putting it there because the book is set a couple weeks later in the summer than the picture above. But I still think it's plausible.
