Don’t pack your fears. If you pack so you’re ready for ALL possibilities, your pack will be stupid heavy. I do keep extra stuff at my truck and will make game time decisions based on what the weather is supposed to be, but I still try to be very deliberate with my decisions. I still have my Columbia wools from 2006’ish. I love them, but they’re heavy to haul around. Rain gear and puffys are lighter and store much better in a pack.
