But you can always go on a leprechaun hunt, so that's just what we did! We found lots of clover, but no leprechauns.
We came inside, did a quick Google search, and watched the short film Leprechaun's Gold (1949).
The leprechauns in this cartoon washed their gold, and that reminded me about this science activity that I'll suggest later this afternoon or tomorrow. (Update: We did it! You can see that post here.)
After lunch we hit DLTK's sites, and when Gerrick spotted the spinning shamrocks, he had to play this game. His prize from this game was a couple of coloring sheets. (He insisted I print them.) While he is working on those, I just found these other St. Patrick's Day activities that I'll offer to him later today and maybe even tomorrow.
Hope you're having a Happy St. Patrick's Day!
