So I fished hard on Friday 9/23/2016 from 1pm to 4:30 pm at Roaches Run by DC Reagan airport. Didn't catch anything until the very last minute. Patience rewarded me with this 21 inches snakehead. He was so hungry and swallowed my frog deep down in his throat.
This is the small white frog I used - Lunkerhunt LF05 Lunker Frog Series 2.5-Inch Pearl Style Fishing Lure - buy from amazon to get the best price -
