Wow! I love sunflowers! They are such a cool flower, and somehow they just make a person smile!
So that's so awesome that these are not too far from your new house. There are some sunflower fields in SW Colorado that I like to photograph, and also some up in South Dakota that I have discovered. You are correct that they move where they plant them from year to year, so each year it's kind of fun in trying to explore and discover where they got planted.
#1 is awesome! Love how you composed it with that opening in the hedge having a view of that mountain peak in the background. Great eye on your part. I like the detail of those sunflower before they opened. I haven't shot that myself, but those are really cool. My other favorite is that pano image, that makes for a cool pano.
I need to come down and visit you! You really live in such an incredible area.
