Thanks one and all. I surely do appreciate any and all thoughts.

Good point, Frank, I do believe I've had a little drip down there for a while and, truthfully, because I had several issues going on at the same time, I folded up the hose, tied it off and forgot about it.

Time for a revisit.

I believe the game plan should be:
1. Check all hoses for rubbing.
2. Check for pin holes (if I can).
3. Replace the coolant overflow jug. It's 20 years old and might just have a leak which would explain why there's never any coolant in it. I've seen no evidence of dripping down the inner fender, though.
4. Replace radiator cap.
5. Replace small hose from radiator neck to overflow jug.

If anyone has anymore ideas, I'm all ears. I'm getting a little tired of chasing this damn leak.
