Keep ice from melting so fast
Ice can get expensive, especially on a fishing/camping trip. We learned a trick a long time ago from an old guy we met. We were on a long fishing/camping trip and had caught a lot of trout. It was very hot and we were going through ice like it was going out of style. This nice old guy saw us purchasing about 10 bags and asked why we were getting so many. We told him and he said "Oh, I guess only us old folks know the trick". He took a cup, filled it with ice and took out some salt. He poured the salt over the ice and before our eyes we saw all the cubes become one. We were impressed. \ \ He went with us to our fish coolers and had us take everything out. We then layered ice with fish and salted each layer. It created one big ice cube with fish inside. I don't think we had to buy ice for that cooler for the rest of the trip....simply amazing!
