well, the shelters are about 10 miles apart for starters, for planning purposes (except in snp) and usually have tent areas in the vicinity.
pro tip - treat a hot spot on your feet immediately, with a piece of tape or bandaid, don't wait for the hot spot to get worse.
you don't have to carry more than 2 liters of water at most times, plenty of creeks to fill up.
try to keep you pack weight under 35lbs.
slow, steady pace wins the day.
