Leaving Boston on 9//22/17 and going to spend 1 night in Portsmouth then head toward Portland to spend 2 days. Any suggestions for either city would be great. Can we drive a scenic way from Portsmouth to Portland? Want to eat some good seafood while there. Mainly just to see the area since never been in this part of country. I know 4 days is not enough time to really see much but it had to be a short trip and really got a taste for the sea food that we hope to find there. Any advice or help will be appreciated.
