The Federal Reserve in Kansas City

Saw that there was something called the "money museum" at the Federal Reseve building, it was free, so good to go.  I remembered it was obviously a Federal Building, and as I walked in, there were no less than 6 Federal law enforcement types, complete with an overweight Supervisor keeping things all proper.  I was told to produce ID, and I assume they ran a background check, and then they made up a badge for me.  All this to go to a free money museum, which was on the first floor.  Then I had to go through a metal detector, then had to sit and wait for my badge.  Then off to the museum, which was actually pretty interesting.  There is a section where you look through glass at workers processing literally carts full of bills, a sign says a cart is worth 675,000 if its dollar bills, 64 million if its in 100 dollar bills....They don't allow photos, of course.  There is also a display of the various coinage and paper monies that have been used over the years.....  I got a nice pin, and off to the next stop
