Aside from the ones in Thailand with WhiteThaiGer, I have one in AZ. Is this thread only for successful visits? Because
this one wasn't successful, but it was a great trip.
Two of my most interesting confluence experiences involved planning for confluences that had not been visited and documented. One of them was the one in AZ (above) and another was in Mexico. On both accounts, we did extensive planning for the trip with recon' missions ahead of the actual visit. And both times, someone beat us to it. So my advice is, if you are planning a trip to an unvisited confluence, don't post your plans in public, and hurry up!
