A couple of good ones:
First, it's the feast of St. Gaspar del Bufalo, founder of the Missionaries of the Precious Blood. And yes, St. Blog's has its very own Precious Blood blogger, who, of course, has a lot about St. Gaspar today.
It's also the memorial of St. Margaret Clitherow, martyred for harboring Catholic priests and having Mass said in her home. Martyred by means of a big door laid on top of her and big rocks piled on top of that. Oh, those civilized Brits.
