Neighborhood detention pond is the closest (500′) although not exactly a natural water source. There is a lake (.6 miles) and city park pond (.2 miles) near by as well as other detention ponds that would be less stealthy. Soda bottles in an backpack, and a bucket w/ a lid. More importantly after you get your water how are you going to make it drinkable? You wouldn’t want to contaminate a transport container w/ non potable water.
