The loggerheads are the best. The are the largest and have the most meat. They largest recorded alligator snapping turtle is in a restaurant near my folks house; it is over 500 lbs and 150 years old. :shock: I am still not sure why we call the alligator snappers "loggerheads" in Louisiana. Loggerhead turtles are really a salt water turtle (a completely different type of turtle), but for some reason, we ignore that in Louisiana. But they are good to eat. If you do not cook it right, the sauce can come out very oily and it will give you 3rd degree heart burn.
We bait the traps with chicken parts - the cheap way. ;-)
