Yolk - you have a source, a pleasant 11 drive away. You're welcome out here anytime. Have Hudland YP growing out as we speak, and they need a good home.
FYI - my YP population also suffered upon introduction of HSB, SMB, and WE. Now I have a 1/3 ac pond specialized for trophy f YP and m BG in order to get my fix. Hoping you won't have to go to that extreme - but if you want any feedback or direction should you consider a specialized fishery similar, I insist you call me and take all the time you need.
