Going up or down a mountain does not prove the world is round by itself, no matter how twisted the road might be. Take for example most 3D game worlds, which are generally simulated using a flat-world for ease, but still simulate gravity (and sometimes even the horizon) just fine. If you find somebody determined to not trust evidence such as the blue marble photos, it can be quite hard to prove that the world is not flat. The major issue comes from the fact that, at a human scale, the difference between a flat world and and Earth is very small - you don't need to take into account the curve of the earth for almost any buildings. With that in mind, I'm not sure what evidence you claim is "blatantly obvious". By far the two simplest evidence is traveling around the Earth (not particularly easy, especially even 100 years ago) and watching the stars move. Both could be explained by other methods, but those would be vastly more complicated to explain the observed behavior (look at the Earth-centric universe models).
