It's interesting how, especially late winter, just when you think there isn't a fish in the lake biting, you meet up with some guys who just smoked them, both in numbers and size.
And, from the opposite side of the equation, when you've had a fairly good day, you meet up with friends on the water who have netted a "0", let them know that in fact there is a bite going on and, with that bit of inspiration, they turn their day around with some solid fish.
Just keeps me always thinking that, "They're biting somewhere. Find them and get a bait in front of their nose."
