I don't know if anyone over that way is reading this blog, but so many Americans will be affected by that terrifying tornado that has destroyed so much.  The news item I read states that there are likely to be more twisters - God forbid they are as bad as this one.  My heart aches for you all.  Why is Nature being so cruel this century?  Is it payback time for what humans have done to the planet in the past few centuries?
