No, I haven't been to the Southwest though I really want to see it, so you can disqualify my answer on that basis. It is, however, pictures of the formations of the Southwest that convince me the most of the Flood apart from the Bible. The stacked strata, so obviously rapidly formed by water, the fact that all the formations are shapes of stacked strata exposed by what looks like massive water erosion, and of course the incredibly copious fossil contents.
