The postal museum is not a D.C. highlight and unless you are like my husband and have a fascination with mail then I'd only visit if you have the time or live in the area.
And people these days get mad when the mail does not show up in 2 days
Go for a carriage ride
Kyle looks thrilled but Tavish is enjoying the ride
Hanging out with a new family
Deliver the mail by truck
I want a ride
By road or air or sea (no boats here though)
Most of the exhibits were pretty interesting but some of the stamp collecting ones were boring but I'm not a stamp collector. I'm not sure that we'll go back but it was worth a look if you live in the area.
