Coloring Eggs

In preparation for our Easter trip to Monticello, I cooked 6 dozen eggs to be rolled down the rock hill at the cave.   I waaaaay overcooked my hard boiled eggs, but I figured since they were just rolling them down the hill and wasting them, I didn't care that they were like cement.  I have to say my eggs held up remarkably well being thrown down the rocks, and my yolks were intact! :)  When we were finished coloring the eggs, the kids said "that's all?"  Sheesh.  I usually only make a dozen or 2, so you'd think 72 was enough.
