You may have planned your trip to the umpteenth degree, but Mother Nature has ideas of her own.
When you enter the wilderness by all means be as prepared as you possibly can, but at the same time go with an open and adaptable mindset. Schedules that are set in stone are rarely a good thing when it comes to backcountry travel.
Find a balance between the planned and the spontaneous. Your trip will be all the better for it.
