When I lived in Germany for a while, my wife and I took a train across the country one winter to Munich for the Christmas markets. We stayed in a hostel and walked the streets, enjoying the various stalls. I'd never heard of Glüwein before (hot, mulled, spiced red wine), but it was fantastic! It was an amazing experience and we didn't have to worry about parking lots or figuring out public transportation. Everything was within walking distance and we ended up touring all of Munich on foot.
I wish the US would get off its ass and get some high speed trains set up. We just need to keep oil and auto dealers out of the discussion because they keep shutting it down. Like Musk's "Hyperloop" project, which he proposed to stop legislation from approving high speed trains, but then intentionally did nothing with, so we just don't develop trains to replace his Tesla cars.
