is there a way to catch trout with no real hatch going on? I go one day there are birds working but no risesand tons of bugs coming up. i catch 6 fish and miss just as many on nymphs.I go back and theres no birds and no rises for acouple days. i struggle to catch any trout on nymphs. i know they are there, how do you catch them?any good nymph combo to try at that point? thanks
