There were so many signs I didn't get to read them all.
I don't think there was one that said that and I did n't have room to take any sign with me, I had a car load.. But one really cool sign, and I am not sure how they did it was made of lights in the shape of a big W, and it was lit up.
Funny this thread popped up. I was on playground duty about 4 miles from where the lion escaped. When I came in the principal made an announcement that recess was to be inside. I walked up and asked him what was going on and he said there was a lion that was loose near us so he wasnt taking any chances. I asked him what I was expected to do if a lion showed up on the playground? He laughed and said he would have to check the student handbook and emergency response catalog for that!
