Most times, if I remember, I pack an extra meal for dinner if I know I'm gonna head to the river after work. I'll get to the river, sit on the bank at the first location I plan to fish and eat. I like doing this because it let's me kinda plan my approach on that particular piece of water. I get to see what bugs are flying around me, as well as watching the water and seeing if there is any activity on the surface, which saves me from just jumping in on a feeding trout.
