Don't do it just for "the climate". There's something magic about sail and rail. Traveling this way makes the world feel immense. And it is. We just mostly miss it now riding in sky-cans from one Starbucks to the next.
We've also discovered far, far more nationally, and a lot of jewels off the beaten track away from the famous and touristy.
We'd miss that if we started going by air again. We mostly don't want to.
Will never forget the owner of a small camp in rural Spain who didn’t spoke a word of English and was sooo excited to see foreigners that he fed us homemade grappa basically until we dropped. His treat of course.
Or the random village on the border of France and Belgium where we had a flat and had to ride our longboards into town and mime to people that we need help. They got us a tow truck from 2 villages over on a Sunday. All without us knowing a word of French or them a word of English.
Don’t waste travel time folks. It’s the best part of a vacation.
Sure beats 2 hrs in departures. :)
