It's tough to answer that. Most people think of wide angle lenses for landscapes because they want to take in as much as they can. Not long ago I picked a few dozen of my landscapes and put them in a folder to use as wallpaper on my Windows computer, setting it to rotate through them every half hour. I set it to "fit," meaning the images would fill my monitor, necessarily cropping the images as needed rather than leaving black bars to fill any gaps. I was amazed how much better many of my images looked cropped! Wider is not necessarily better.

I also recently read an article in which the author listed the focal lengths he uses for 'scapes and the percentages he uses them. He shot more in a portrait length (about 75-105mm) than any other length.

So you might consider a traditional wide, or if you go that way, an ultra-wide (on your camera, that would be down in the 11-16mm range). In that range Rokinon/Samyang makes some excellent, low-cost MF lenses! Otherwise, a decent walk-around lens like the Sigma 18-250mm Macro would give you a nice range for every day and landscapes. While not a true macro, it has better IQ than others in its class (it sometimes fools me into thinking pics I took with it were taken with my G glass!), and the close focusing distance allows you to stop down, use a hyperfocal focus point (look that up on Google), and thereby add some close foreground interest to add significant appeal to your landscapes.

Really? When I visit south western USA, Along with the Americanized English, I hear lots of Spanish. In the northeast I frequently hear German and Russian spoken and then there is a form of Creole spoken in parts of the great state of Louisiana.
Not sure exactly what language some of the good ole boys in Tennessee speak. Then of course there are all the different languages spoken by the native Americans (the true Americans) the rest of you like most of us Canadians, imported from some other country. The USA, like Canada, is a melting pot of nationalities with a mixture of languages. So, while English is the "official" language of the USA, depending upon the region of the country you visit, you are bound to hear people speaking different languages. But, then maybe that is what you meant when you said..."Here in the states, we speak good ole American".

A useful comment; thanks.

About wide-angle or not:

1.
California impressionists painted mainly landscapes, exploring light.
Looking at mine, they are roughly the shape of a piece of typing paper in landscape format, but less wide -- and in one case nearly square. The one I have by the top female of the genre is in portrait format! I'd not observed this pattern before and have not seen such a comment elsewhere for the genre.

2.
To reinforce, I was looking at (drooling over?) the Nikkor 45mm PC-E last night; not so wide, right? Nikon trumpets it for nature. I'm doing the math: there are by definition more good outdoor images one can compose with a 45mm 1:2x than at 20mm.
