I couldn't agree me (as the saying goes).
So, basically, I JUST signed up. Because I was DDG'ed to Digger's question in this thread.
Only after signup now, I realized how Digger's thread digressed.... Not good. I guess we all agree on that.
If an OP asks a question (route, wife, horsebet, doesn't matter), I'd like to keep with the question. If I know sth to answer, I may write it. If I have the same question, I first sign up.
(OMG, I love the smilies here! I had the same gorgeous selection on one of my early sites. I missed them. - Now people call them emojies. So what?)
NOTHING MATTERS, guys and gals.
"we will be all alike in less than 100 years, so let's please revert back to more important things - Digger".

Humor aside (mine): I too am looking for a "good" road trip from north to south Portugal. (Doh! You wouldn't have guessed ) Hence how/ why I found this forum.

ONLY two differences: I won't be going on a pedal bike, but bike with emotor.
2nd difference, you are missing?
I don't have a wife in a car to join me. Maybe we find us here? Who knows.

Okay, SO: Most of you seem to agree, I should be going "near the Spanish border". Boy, I like the ambiguousness of that advice! Spain is safer, okay, I got it. Just joking - as always.

I finish my post when I got through all the smilies.




Nah, NOW!

PS: I still have to read the "policies", if e-bikers are allowed here at all. The paper-map users know: Bikemeansmanythings, and I wouldn't want to attract harassment for not pedaling...
(That was the final smilie, yeah baby!)

PPS: Anyone who shares my endless humor wanting to join me on the trip?
My PLAN is 2 days, ie with one recharging overnight stop. However, I am blatantly open-minded and flexible: If the trip shall take a week, it can take a week.
Portugal has a LOT for sightseeing, years ago I traveled "all" of it, by truck, with my tiny house on it. Yeah man!

PPPS: The return trip needs planning too: A month or so later, I will be needing to go from south to north. Cheers.
