If you don't have a roll-up door, you can always console yourself with this recipe for chocolate almond bark from All Recipes. The ingredients are simple enough that even I can understand them: chocolate chips, chopped almonds, and shortening. It's the middle step, from ingredients to finished product, that always confuses me, whatever the recipe.

Here, from National Geographic,  is a nice photograph of a PC400 excavator hard at work on a demolition site, unloading a bucket of cement rubble. And here, from the same site, is a photo of a set of demolition shear jaws ripping electrical wiring from Busch stadium. This site's home page always has something interesting.

No worries.
