I'll have to drive an hr and a half each way to get it. He says it's all been properly stored and no issues. Expires 2034. Should I get it.
Sounds like you're on the right track to me! I don't have a nearby creek/river but I do have about 40 gallons of water in 5 gallon containers. It's tapwater which should be fine since it's been treated, but I can always filter or whatever if needed. Otherwise I just swap it out a couple times a year for "fresh" tapwater.
