We do but travel is kind of a pain in the ass and it kind of takes forever (in comparison to just driving). I've ridden buses a fair bit and have had consistently bad experiences. Culminating in my last trip. Was supposed to be an 8-hour trip (1 hour layover, but it's only about 5.5 hours by car), and it ended up taking 15 hours. Was a bit of a fluke in many ways, but the fact that I wasn't even that surprised should tell you something.
I've not tried Amtrak or similar so I wouldn't know what to expect or even how to get to a station but I suppose it's worth looking into.
