Leaving paw prints

Usually by February, I am sick of winter. The gray. The taupe. The blah. This year, however, we had some snow (never enough) that has actually stuck around for a while. It's so nice to see white, especially in moonlight.

Animals leave tracks in snow. These were on my front walk. I am guessing it was a fox, but it's difficult to tell, as each print is a double; the animal stepped into the same paw print with its hind leg that the front leg made.

I was hoping that Burpee would send my lettuce seeds ahead of the plants I ordered, but apparently not. I'm anxious to try growing lettuce inside. I may purchase some seed locally, just to get started.

I came across the following graphic somewhere (FB?) While the idea of growing plants in water is intriguing, I have questions.

I have taken cuttings from plants and rooted them in water, but then always transplant them into soil.
