cooler and xoconostle, Thank you for the information this is exactily what I was looking for. It fills in the gaps sufficuently so that I can get something going on this. Since I found out that trout exist in Alaska, 33F or even cooler is probably not out of the question, but I'll bet they're freezing their booties off. bikermouse anticipates a question - Q: what is a bootie is and/or where it is located on a trout? A: I dunno. Thanks again, - TJ
