Well, "weakly" is in the eye of the beholder. You can do a lot of different things with photons where the interaction does not seem weak at all. And you can have other particles (electrons, protons, atoms) that travel without much interacting with the environment as well.

In my book, neutrinos are the ones that are hard to interact with. Requiring of course the weak force.
