Chances are you have some (often many) dandelions growing in your yard, too.
As to the best time to harvest the roots, here is one link on that subject, too: http://commonsensehome.com/harvesting-and-using-dandelion-roots/
And even dandelion tea, as I call it, is now even offered for K-Cup brewing.
As a Marine, anything warm, like chicken Ramen soup, or warm coffee or tea, is good for morale when one has to patrol or otherwise stay awake and alert in the middle of night, especially during foul weather. The expectation of something warm to consume is always good for morale, so keep that in mind if you are on the cooking side of home security.
