I haven't been to Portland in years, visited often in the '90's. Downtown is interesting, they have a great bus system I used to get around town, small cost and you can ride for hours for not much money, to different locations. I enjoyed the zoo and surrounding areas just a short distance from downtown. There are rose gardens, landscapes etc., downtown will also give you access to the rail system to travel east to the waterfalls, etc.. The bus drivers have good tips for photos and were helpful in getting me on the right bus. If you need a place to sit and rest with a cup of coffee there is always Powells bookstore, walking distance from downtown. It covers a block and is several levels, used books as well, at good prices. From downtown you can also access the river and some of the older buildings. If the transportation info. is incorrect I'm sure one of the apuggers in the area will let you know. Dan
