Starting in Texas, with a goal of riding paved roads for 30 days, and seeing as many of the 'biomes' as possible- did I get that right?
Well, the USA is a pretty big place, so I'd recommend focusing on two or three states (or less) and give yourself time to really do some exploring. I've lived in Colorado most of my life and never get tired of the riding here.
If you were to concentrate on the Rocky Mountain states of New Mexico, Colorado, and Wyoming, each state, by itself, would easily yield a good 30 day trip. But if you did include the three you would have low desert, high desert, juniper/pinon forests, ponderosa pine forest, high alpine and tundra to traverse.
You could also spend time on the Great Plains ,although that would not be my choice for good riding. I usually ride out there in the winter when the mountains are snowed in.
