So, long story short, I might become homeless again in the next couple of months. I've been thinking about building a hidden shelter in some random-ass part of the park (or other wooded, secluded area: the parks may be too well traveled). Any suggestions for building a shelter that allows me to store stuff and keep it dry, can be discreetly built (supplies will have to be carried in a backpack or duffel bag), and will allow me to stand up and lay down with room to spare. I'm hoping to have it built before the snow falls (snow tracks to the shelter could be an issue, hmm....).

Pic related, it's more or less what my initial thoughts were, but I'm fearful of standing water being an issue.
