We have a winner!

Yay Heidi! She guessed early this morning and was right. They are seeds blowing from the microburst winds we had Tuesday(20th) evening. Great job Heidi, rolls are coming!
Here is a video of that day, it is not the best because I move around a lot at the end but I love Catherine's excitement! It was cool to see all those seeds flying around. This video was one of the bigger gusts.
