Thank you for the post. I am walking from Washington DC to Pittsburgh in September along the C&O Canal Towpath and the Great Allegheny Passage, about 300 miles. There are towns along the way and plenty of camping sites.
I walked VDLP last March until i stop due to COVID. I flew to Madrid and took a taxi, there are buses available, to the Atocha train station. There are trains to Seville every hour on the hour. I arrived to Seville in time for lunch. Buen camino.
