Boston
I went to just-outside-Boston for a work trip! The work bit went well, and we had a free day at the end to go and explore Boston. It's a nice place, I was surprised at how low-key and unhurried it felt. Sure we were there on a Friday morning so maybe not a busy time but it was all very walkable and relaxed anyway.
I think I'd only been in an Uber once before (it doesn't serve where I live) and on this trip it felt like twice a day.
