Okay, here's one for Capt. Bill Judd, or Dale, or Jim. I'm heading down the Ohio River. I know about old Lock #37 (Fernbank), #38 (Maxville/Belleview), #39 (Markland). I know McAlpine at Louisville was #41, renamed. The next one below that was #43 above Mosquito Creek. Here's my question: Was there ever a Lock #40 or a #42?
