No, you don’t want to find out. Unfortunately if you’re caught in a storm there is no way to minimize even slightly the risk of lightning hitting you. Lightning is a large scale phenomenon miles and miles long and not influenced by objects on the ground. Especially small objects like a blind. A lightning bolts connection to the ground is predetermined long before it knows what’s on the ground. If there’s a tall tree in an open field it might hit it or it might hit 100 ft away. It’s completely unpredictable, as is it’s path. I’ve seen lightning act in so many strange ways many times working in the electrical field. The only way to avoid it is not be there. I will also say that even if the metal around you did provide some kind of path, you would still be hit so to speak with side splash. That’s how most people get hurt anyways. Direct hits are much more rare.
