Mystery solved! The leak was coming from the only place under the hood that wasn't drenched in coolant- the upper radiator hose connection at the radiator. There was coolant on the bottom of the engine, the back of the engine on the opposite side, behind the water pump, on the top of the air cleaner, etc.... but it was bone dry and clean where the leak was. I only found it after buying a pressure tester and pumping it up to 20 lbs. I looked all over and never found anything, but my brother noticed one droplet fall from there. I tightened the clamp a little, road tested, and no more antifreeze shower. Sometimes it's just the little things. Maybe my water neck bolts were leaking too, and I fixed that along the way. Who knows.
