I really wanted to take a train or greyhound, wasn't super picky, for my last two trips but it was stupid. I had naively assumed the tradeoff was going to be adding about two days to the trip for travel there and back but in exchange it would be a lot cheaper than a flight. Nope. I guess. For some reason. Same travel days, same destinations. Not only were flights, obviously, faster but they were cheaper too.
Pay more for fewer departure/arrival options and turn a few hour hours into +1 day on each end seemed not worth the vibe.
