Hey Bullhead...yea that string deal was more joke/hoax than anything else...I have tinkered with paddlewheel type things powered by various stuff and placed front & rear & mid...kicked up some water but very little actual movement. As far as the chick thing ...absolutely no joke...I have an old VHS tape we made one day that recorded the whole process from chick softly plopping down to the strange almost surreal sucking sound as a 9LBer just eased up under it flared her massive gills and GONE!! If I can find it and figure out how to transfer it to some kind of uploadable format I'll post on FB or Utube. I love a good joke but the truth is always stranger than fiction. Bob who??
