What do you guys use to keep your shad fresh during the hot days of summer? I normally use an igloo cooler packed with ice but the ice seems to melt pretty fast and my bait gets saturated in the cold water and I don't feel it is as good when that happens, I've also tried putting ice in my livewell but that seems to melt the ice faster. I'm thinking I just need a better grade cooler. I tried to tell my wife I need the 20qt Yetti but she shot that down quickly when she looked at prices and what I would be using it for. Any opinions or recommendations are appreciated.
