Lots more photos and some animations. It was raining pretty hard today which meant the air was dead calm as soon as the rain stopped, this let the rings fly for upwards of 10seconds before hitting something or getting so large that they disappear. The rings start at about 10km/h and their speed drops off to some where around 5km/h. Once they have slowed down they are very stable and will fly for a long time. With the help of my brother I was able to get some edge on photos that show there are 2 rings of smoke in each smoke ring and that the center of the tight ring is hollow (not really news). Enjoy the photos and post any questions you have.

At angles views
These show the tight inner ring as well as the lose outer ring that trails smoke.
The light green tree on the right is ~52 feet from where I launched the rings. The rings hit the tree and russled the leaves enough to knock the rain off of it.

Imagine how much money you could sell those photos for on a UFO buff group.
