Most of the road surfaces were excellent, especially on the tunnel route.
There was a longish stretch of rough tarmac on Hwy 35 which made me curse the Al frame and skinny tyres (I normally ride a Ti frame on 35Cs so no wonder
).
I'd certainly recommend visiting the area.
Hood River itself (ie the town) has 3 micro-breweries in it
, some good restaurants, several places to taste the local wines and the bike shop rents out some very classy bikes
If you like trains and beer you'll be in heaven- the Union Pacific line runs right past the Full Sail Brewery's pub window and across the river is the BNSF line.
I had a good time there
