I have crystal geyser gallons frozen in my freezer right now and thermal bubble insulation in my 2 pre chilling coolers (with 108 beers.) 😄Try an image search for Crystal Geyser 1 Gallon. Their bottles have a square shape that makes them ideal for packing in the bottom of your cooler. We packed the bottom of our 110 L igloo cooler from 1998 with a couple of those bad boys, and with a wet towel covering the lid, we still had cold ones by the end of our 95 mile trip down Cataract last fall. Additionally, search cool shield thermal bubble roll. They sell it by the foot at most hardware stores. A sheet of that between your lid and the cargo will save you big time on losing your chill.
Hear hear. My thought is that with good cooler management, wet towels (or paco pads) over the coolers & a day cooler you should be fine. I'd freeze good drinking water in jugs and then just decant ice-cold drinking water periodically. I just don't like the idea of wasting cooler space with such bulky stuff that you can't eat or drink.Why waste water with that kooler gel crap. Just use the melted water as it melts for ice cold drinking water.
"According to court documents, CG Roxane obtained water by drawing groundwater from the eastern slope of the Sierra Nevada mountains that contained naturally occurring arsenic. The company used sand filters to reduce the concentration of arsenic so the water would meet federal drinking water standards. To maintain the effectiveness of the sand filters, CG Roxane back-flushed the filters with a sodium hydroxide solution, which generated thousands of gallons of arsenic-contaminated wastewater."Interesting lawsuit against Crystal Geyser:
