Yes I decline the water bladder style simply as it is harder to clean , sterilize ; I myself carry those accordion folding water bladders, they zip ultra small and light but can carry half a gallon. If anyone is going to buy those water bladder bags please buy the type with the wide opening to make cleaning somewhat easier.
And thank you for the tip, but living in Florida means any travel would not be a day time activity usually. Every afternoon we get thunder storms and lose ( my guess only ) 14 people to lightning strikes , probably not a bad way to " pass-on " in 'reality ' ! ! !
