Depending on where you live, you may not have access to a fountain by the time you need more. I carry around slightly less large bottle (1L) and you can bet your ass I had gone through it on the days when I had to be outside in 100+F/38+C weather for hours, and I got home thirsty. It is way better to have too much water and not need it than to not have enough and need it.
