I was in a small village in WY (pop 17; nearer 1000 on the day) that had a post office; I queued up for stamps to be told that they were only valid for the US and only available in sheets of 24; so managed with lunar eclipse ones from 2016 instead. The lady had designed a special cancellation stamp. Some enterprising charity outside was selling pre-stamped envelopes for $5 but the lady sold me an official USPS envelope for 61c
It's not arrived yet; neither have the postcards, the only slightly eclipsey one I could find was Wyoming Sunrise (so I wrote on the back even better when there are two in one day!)
I could not believe the number of people (both US and a few UK tourists too) who were so close but didn't bother travelling to the zone of totality. One (rode alongside him in the Rockies) worked in the solar industry and knew full well that a 99% eclipse was still the equivalent of a well lit office.
to quote Patrick Moore; "seeing a partial eclipse rather than a total one is like going to the opera and standing in the foyer"
fabbbola!
but the encroaching darkness was nothing like as eery as the almost clouded out one in Devon 1999
