Thanks for the ideas, guys!
I should have been clearer in my original post. I am looking for a water jug with the water in it! The jug is brought to where there is no potable water -- think a primitive cabin, a boat, a picnic out in the middle of nowhere.
I am kicking myself that somehow the jug we used years ago was... what? Sent to recycling? If I remember correctly, that is probably what happened because there was no top opening to refill and you could not unscrew the spigot. The jug with water in it cost probably around $4 or so.
Those jugs from Amazon are gorgeous but out of the budget. Maybe I need to break down and buy one and it will last forever.
I will post what I come up with for a solution. Thanks very much!
