First off we have a small creek that runs through our city park which is about 1/2 from our house if we walk straight down the street but if we have to stay sort of hidden, we could go a round about way and stay in the tree line.
We would use our back packs that have bladders, if we need more than that we could use a wheeled cart.
We also have Sawyer filters on hand to make sure it is drinkable.
