In the last hour I fished I landed 3 mirrors and 2 commons. These fish were all taken on hair rigged sweet corn. My best producing bait combo was a kernel of regular sweet corn along with a kernel of pineapple flavored Pescaviva fished off a hair rig with no method. In the past I have had good success in the early part of the season with that bait combo.
From experience I will tell you that you just never know how fishing will turn out at this time of year. Yes, it's a crap shoot. Sometimes they hit in the cold, and sometimes they don't. Tonight they were. The last three evenings they weren't. So, I guess the message here is that you just have to get out and fish and hope for the best.
