The super cool curvy cloud was on the edge of tornado producing storms that occurred about 60 miles north of my house on June 12th, 2013 . The edge came right to the edge of my neighborhood. It was pretty cool. It felt like an enormous spaceship floating above. The photos do not do it justice. The 3rd photo is from yesterday, glass by Dale Chihuly, at the Franklin Park Conservatory. Pretty darn cool if you ask me.
