So Jeremy Wade and his crew have been down in Addison filming an episode of River Monsters... For what? Beats the heck out of me.
"I am Jeremy Wade and I am fishing for a fish that has killed dozens of fishermen by having them wake up early eating greasy breakfasts, giving them sunburns and frusterating them until they have heart attacks or diabetes or aneurysms or skin cancer... The Smallmouth Bass."
Seriously though, my bet is that they got word of the Pirahna or Pico that got caught in the area (20" or something) and doing a show on invaders/aquarium dumped fish. We have great fish up here, but nothing that isn't dramatically bigger and more abundant in other areas of the country.
