My son has been fishing Albert Lea Lake(that's the lake you cross on I-35 just north of the Iowa border) and has been nailing the walleye's. They have been between 16-21". He said when he drops the Aqua-Vu camera down you see walleye's everywhere. I put some pics here of his last 2 days catch. http://minnesotaoutside.blogspot.com These are just the ones he's kept, released most.
If you've got short, stubby fingers and wear reading glasses, any relaxation you would normally derive from fly fishing is completely eliminated when you try to tie on a fly. ~ Jack Ohman, Fear of Fly Fishing, 1988
