I fish the Trinity here in the DFW area. Lots of huge carp.One time, I had two on at the same time. Luckily, one was running downstream and one up. I had to alternate hitting the freespool on the two Zebcos loaded up with 6 lb. test, but eventually landed aboth the 8 lb. and 12 lb. carp.
A few years ago, they had the San Antonio river dammed up and the water redirected while they did repairs downtown, and I saw a good sized crappie sunning in the middle of downtown.....soooo, they're in there, the rest is up to you!!!! LOL.
I may be slow, but I'm catching more than YOU!
