What personally-viewed evidence have you seen that the US Postal Service is doing less business than it used to? If you haven't seen any, what evidence have you seen otherwise?

I’ve seen evidence to the contrary, but I realize that my anecdotal observations aren’t necessarily indicative of the overall economic status of the USPS.

Here they are anyway:

I went to my local branch last 2/22 and the line was almost out of the building.
It was at least as long as any other line that I’ve seen there, and I’ve been going there for about 20+ years (it might be 30, but that office might not have been there when I got my house 36 years ago).

Today as I was trying to deposit a letter in a box near my house just before pick-up time, I had trouble opening the deposit door because it was so full of mail.
