Here's a bit of technical stuff for those who may be interested. I use a Canon 30D and these photos were taken with a Tamron 18-250 zoom lens. Each photo consists of around 8-12 separate images stitched together in Photoshop Elements. I had to remove a few spots in the sky caused by some dust on the sensor and made some minor adjustments in the levels but other than that what you see is how it looked to me on the day. The shots have been resized for web display. You can click on the image to open a larger view.
