Holland, the Netherlands. Good food, good beer, pretty girls (and I don’t mean window shopping), plus most of the locals speak English. I’m true blue American - I speak 2 languages, English and bad English.
Wales. Good beer, mind warping language (but you can get by in English), lovely countryside. Some of the most friendly people I’ve ever met.
Germany. Good beer, good food (I like German food over French food, YMMV), mostly friendly people, lovely countryside, plenty of history, and the Autobahn. For a car guy, there’s no place better this side of the salt flats. Make sure to read up on the rules of the road. They can be real Naz… well, let’s just say they take lane control very serious.
Israel. The joke is ‘what is the difference between (British citizen of some type) and an American? The (British citizen of some type) thinks 200 miles is a long way, and the American thinks 200 years is a long time’. In all of Europe, I’ve been in spaces that were defined for hundreds of years. In Israel, spaces have been defined for thousands of years. There are other places in the world you can experience that, but not many.
In the good ol’ USA - hey, drive a coupla E/W interstates. From the mid-Atlantic to the left coast is about 3000 miles. That’s about the same as Lisbon to Moscow. One language, one currency, no customs, no passports, and, depending on the direction of travel, no checkpoints (California doesn’t allow some agricultural products to come into the state). I-40 for the desolation of the Southwest, I-80 for the farmlands and open skies of Wyoming (the sky is bigger there, don’t ask me how). Better food on I-40. Not that I-80 has bad food, but I-40 is just better. From BBQ to Tex-Mex, they get it right.
