My husband and I are in the early planning stages of our first trip to the Oregon Coast in late September. Is it better to drive the whole coast or can we do just either the northern or southern section and then do something else perhaps in Portland or Seattle? We love the outdoors and beautiful scenery, however, we thought perhaps it would begin to all look the same after awhile. Also, if we were to pick one section, any thoughts on which section is better? It will help us to determine which airport(s) we would need to fly in and out of. Thanks in advance!
