Get to a place with good water (above any flood planes), not too cold, not too hot, ideally with fruit trees, trees for wood as fuel, and critters around.
Locate water filters, water treatment, firearms, ammo, durable clothing, food that stores well (I remember eating 20 year old C rats when in the military), etc.
Locate some propane powered vehicles as propane seems to have a much longer lifespan than gas or diesel.
If you don't know much about horses or mules and plan on staying around awhile then learn, as fuel will be a problem for other types of transportation a few years out.
Music and movies will be missed. For a source of electricity try to find propane powered generators. Hard to say how long hydroelectric grids will run on their own.
Try to find antibiotics and other medicines with a decent shelf life, store them as best as you can.
Try to locate some tactical nukes to blow the dams. It'd be nice to see salmon running in large numbers in the Columbia River again, and other rivers running free.
