how to use spawning runs

to figure where and how far Biggie travels in his supposed seasonal jaunts.We know that different fish spawn at different times and water temperatures.But we don't know what those figures are or how they would figure in.But it is logical to assume that a creature like Bigfoot would have both an internal clock and past experience on his side to use those dates to his advantage when treking.In theory the fish would be most vulnerable during the spawning seasons in shallow waters and shallow spawning streams and ponds.Here in the upper midwest there is no shortage of any of those.It makes logical sense that it [fish spawns] does play a role.Logically nothing else could sustain him until the vegetation emerges and he can then identify the plants and roots that compose the other part of his diet.Probably wild onions,willows and etc.Moose live almost entirely on willows over the winter.That is why MOOSE migrate.... for taller willow plants. So what about Bigfoot? Those are the million dollar questions to solve this whole big mess.Where the Sam H. does he go and what does he eat there!!!!!????????. So any ideas how to solve all this.Since sightings are unreliable and cooperation is non existant and science refuses to get involved. We keep stumbling over these same mysteries and missed opportunities.It's really quite funny ,or at least will be if someone ever solves it!
