Nobody talking about Thunderbird?

I haven't been out until last night. Went out mostly to try my new sonar. Pretty colors but I still don't know what I'm looking at.

I saw a few caught from the bank at the South Dam ramp. I tried a couple of spots in that area of the lake but no luck. Cool NE wind probably didn't help much. Water temps were 67-68 degrees. Maybe warmer temps this weekend will fire them up.
