We were trolling over some of the road beds at Chatfield. I was using a Berkley Firestick when my clicker started screaming. At first I thought it was a snag, but I was able to gain line on it. It didn't run, just pulled. From the many carp I have caught, I never had one that never ran, at least a little. After a while what ever it was changed directs slowly and went in front of the boat. We had it close enough to the boat to get a net, but it made one last effort and swam under the boat and came off. It was either a really big carp (dark brownish), or a relative of the lochness monster. If I was alone on the boat, I probably would of cried, or possibly dove in after it. I tried to convince myself it was a log so I wouldn't be quite a bummed.
