okay.. just want to say you guys are very good about offering details with some of these questions. been trying to read and write things down. We will be going to Portland this summer. Not knowing much yet and trying to plan a 3 day itinerary in Porltand. What is the best way to see the River Gorge/Mt. Hood and Falls? is there a driving loop around these places? can this be done as a day trip? etc... thank you much.
