First time out on the road camping in many, many years. My road trip covered Maryland to Santa Barbara and back, via I-70 to Missouri and then southern/central Kansas, southern Colorado to NW Colorado, south to Flagstaff and west to the greater LA area (staying with friends) and north of Santa Barbara (camping for 3 days). Return was mostly via I-40 from northern LA to Oklahoma City and then NE to Missouri and I-70 most of the way back to Baltimore.
Block ice just is NOT out there like it used to be. Not in the MidWest and Plains states and not in the SW and California. Not once did I find block ice... in grocery stores, department stores (e.g., large WalMarts), gas stations, anywhere. Not in various campground stores.
Dry ice is not as common as just 10 years ago when it used to be widespread in the Plains and Western states. When I did find dry ice, coupling about 4 lbs with a 10 lb bag of cubed ice would usually do the job for about 3 to 4 days.
Left home with a mix of 4 frozen half-gallon/full gallon bottles of water for cooler cooling and drinking water. Also another four gallons of water for cooking/coffee/drinking, as some areas simply have awful tasting water (and I use these for post-surf rinses as well). These frozen containers of ice took care of me for the first 3 to 4 days on the road.
Wonder if fishing/hunting stores will have block ice? Or it that mostly a thing of the past.
