i've only fished GF for walley a few yrs now. the only spots i know of are around shiloh swimming area. theres a pretty long flat along there, however the last 2 yrs i didnt do very well like in yrs past in that spot. i dont know if they move from yr to yr or what. im just thinking as big as that lake is, there must be many area's that hold walley in mid summer that i dont know about. as for the wife? i've already spooled her reel up with special fishing line. LOL
