#BoringTravel Unreasonably tired, but I didn't sleep as well in coach as I would have done in sleeper. Back in #UnionStation #MetropolitanLounge to relax and cool off. Next train is an hour and a half away.
#BoringTravel <=550 ppm CO2 in the uncrowded upper level of #ChicagoUnionStation #MetropolitanLounge. Just the place to eat my early supper of #bibimbap from #HMart.
* Edit: CO2 was low, not high; typoed the inequality. The point is that it WAS a lower-risk place to unmask and eat.
