down with the decorations

When is it time it take down your exterior holiday decorations?  Here in the Midwest the "polar vortex" has forced many to keep up the outside wreaths, lights, etc. longer than usual.  We keep ours very simple and slightly un-Christmasy to get more time out of them.  With one warmer day last weekend my husband retrieved all the wreaths and lights to be stowed away until next year.
When do you feel is the right time to take down the decorations?
