Jimbo,

A very good point on the knee high boots.  It depends somewhat on the type of boot.  I have knee high Lacrosse "Alpha Burly" knee high rubber boots which I wear hunting.  They are made of wetsuit material, and fairly tight fitting to the knee, so if water goes over the top they don't fill with much at all.  They are not cheap, $90 on sale.The cheaper, loose fitting knee high rubberized canvas knee high boots boots will act like buckets filled with water on your feet.  That is why people have drowned wearing the old style rubberized fabric loose fitting waist or chest high waders when fishing.  A guy I went to high school with drowned in a small pond wearing those old style waders.
