Thanks for the heads-up. We might have a real “surprise” in store for us one of these days. If you are in southwest South Dakota, you are about the same distance as we are in SW Colorado.
Yes, I’m in southwest SoDak., just a few miles from Mt. Rushmore. Prevailing winds from Yellowstone will affect us. If the caldera blows, the whole nation (and world) will be affected. That said, I pray and hope that this is just nothing to be too concerned about.
