Have you ever caught a 4 or 5 foot shark? You had better man up when they make that initial 100 ft run!!!
A 4 to 7 pound Lake El Salto largemouth fights like no other! Their strength is impressive!
Caught several Lake Trout in Yukon, Canada. Took 28 minutes to land and 18 pounder. Great fighting fish for sure. The pike up there are really mean as well!
