I am planning a trip from New Orleans to Eastport Maine at the beginning of August. I will be traveling alone (52 yr old woman) with my 50lb dog in a small two seater sports car. I went to North Carolina two summers ago with the same dog in the same car. It was no problem but this will be a bit more arduous. I am planning on taking at least 4 days. I will return starting on sept. 15. Any advice?
