Last time we were in the keys (now we're talking 1998 - yeah that should date me a bit), we took a charter out and hubby chummed the entire time, along with just about everyone else on the boat except me. I kept giving everyone sips of Coca Cola to settle tummies -but it didn't seem to help. I honestly don't know how the guides do it... So gross! Anyway, we DID catch dinner for that night, and hubby insists it was worth it. LOL!
