I know when we were out there last my buddy was throwing into the toolies with no grass mat around them. I watched a big girl come out of the water but missed it. All his big bites came in areas like that. I have no idea where we were because I don't know the Delta at all. Somewhere around Franks Track i think? Supposedly July is when it starts to happen, and I know Clear Lake has a good frog bite. You met Fred and he's caught a ton of DD on the frog up there too
