Aha! I wasn't alone on PIT-ART. And judging from some other threads, there were plenty of others on PIT-TOL.

I've also done either SDE-ETH or TLV-ETH, but can't remember which. That's in Israel: Sde Dov or Ben Gurion to Eilat. Wouldn't be surprised if another FTer has done one of those, especially a scuba diver.
