There's mountain lions in the neighborhood--did one just walk through?

The weather is warming up, and some trees are budding out. We saw a whole field of daffodils down the hill from our property. But this January was the coldest in fifteen years, so we've been warned. We need to focus on getting the groundwork done for the first large greenhouse, and be able to enclose it before another winter comes, or we'll never be able to plant our guavas, avocadoes, chaya, tropical gingers, and other plants that can't be frozen.
