it’s a fair comment, Portuguese toll roads are expensive, but they are excellent quiet roads, but taking a scenic route like yours you wouldn’t be expected to pay a toll. Portugal is a relatively poor country, and for some reason doesn’t appear to have had the EU finance that Spanish roads seem to enjoy. I’m surprised that Americans would complain as they have toll roads for as long as I can remember, in parts of the US they have to pay to use the outside lane these days!One final thought for tonight. At our b&b we've been chatting with a couple of nice Americans from Atlanta. They've spent most of their touring holiday in Portugal and commented on the incessant toll booths they drive through. None of that in Spain, here is just like the UK, get on the high quality autovias and go as far as you want.
