The other day I was walking around waiting for unicycle hockey to start and i walked into the local gallery and showed the lady at the front desk my yearly portfolio just for fun to show her what I been doing. She knew who I was because been there before and I had my first gallery show there. The back of the book has the photo below, She said thats a microburst and that she has seen and heard about them before. As we were talking I looked it up on my phone and there it was.
