Craig, I know we have hashed this topic over & over so 1 more time can't hurt. As I understand it happens when the surface water gets colder than deeper water. Warm water lighter, cold water heavier, flip!! My question,,,, does this happen in shallower bodies of water. How much does the wind affect,,, slow it down, speed it up,,, negate it altogether? Inquiring minds need to know. It ain't going to help me except to have another excuse why I can't catchem! <*)}}}><
