That's a good question. I hate swimming as a general rule, but if I felt like I could get it back and it was plenty warm, I might. I put my head half way under water to get my castaic baby bass back once when Jamon and I were fishing at Margarita in my boat I got it snagged on some piece of rope. And I carried my float tube about a mile once at Chabot to get back to a spot where I lost a slammer in a submerged tree the day before. I'll go to pretty great lenghts to get a bait back as long as I wasn't risking my life or anything.
