[pct-l] Water Tricks



Thanks Gary
My "normal" conditions are different.  
Hot and steep can double this for me into 2 liters per 10 miles.
Still 3-4 hours isn't bad with a light pack on semi-level ground.  One
liter usually.
Don't try this your first time on the PCT.
Gary's warnibgs are very real.
