Diddit!

"You haven't been to the Post Office yet? Why the hell not?"
Uh, because I don't need stamps?

So I sent out 3 postcards yesterday--finally an excuse to see the famous Post Office. And here it is.
A sort of Vietnamese Grand Central. Designed by the French, or after the French style, built from Vietnamese sweat. The Vietnamese reclaimed it by sprinkling a few of those deco robot people sculptures. Otherwise, it's a post office. It's a tourist spot because it has lots and lots of tourists and no fewer than three gifts shops. 37,000d for 3 postcard stamps, under $2 but outrageous by Vietnamese standards. And a whopping 4,000d to park my electric bike for 2 minutes. But that's one more landmark off my list.
