Thanks! The trick was getting the kids to blow them slow enough to make bubbles large enough to capture.

No, I'm nowhere near a volcano - in the middle of the bald prairie, actually. We get really long sunsets, and right now there is a lot of dust and particulate in the air because it's planting season and the fields are getting tilled. Mind you, just looking through one of my photo streams on flickr, I realized that we get some pretty impressive sunsets in winter too. Must be our northern location. :)
