I haven't been in an Argentina "cloud of dove" scenario, but a few years ago at our deer lease we had an amazing weekend. It was a group of about 8 of us hunting dove in the mornings and evenings while doing work on the lease during the day. As soon as one group of birds would pass, another would be incoming, and from various directions. I'd never seen so many birds in a single day before, even recently my brother-in-law and I were talking about that weekend (especially since we can't seem to find any birds nowadays). It was also the first time I'd used a side-by-side shotgun bird hunting, and I was hooked after that.
