It sounds like you had a wonderful time. I've never been to a sunflower farm before, but now I'm definitely adding it to my list of places to visit.
I love the fact that the sunflowers are planted in a staggered fashion, so there will be plenty of time to enjoy them throughout the season. And the sunflower mazes sound like a lot of fun! I can't wait to see your photos of the farm when it's in full bloom.
