Oddly enough, I have fished w/several people that believe that spit works as a fish attractant.

I took the family clam diggin one morning and there musta been about two dozen or more people floggin the water in search of Dollys. I dug clams, messed around with the family fer quite some time, and did not see any fish hooked. Got my rod, walked down to the water, tied on a lure, of course I lubed up the line w/a copious amount of saliva. You guessed it! On my second or third cast, I caught a nice Dolly -- the only one caught that morn. Wonder if it was the spit?

Sincerely,
Roger
