I just returned from a backpacking trip along the coast in Olympic National Park with my two sons. Think eagles and ferns and otters and rain and beach... You can even have a monster fire on the beach in solitude with the abundant driftwood.
It's easy to forget when packing that the Olympic Coast is a rainforest. It's wet. When the sun comes out it's a bonus and we were fortunate to have a little sun here and there.
