Is it just a little typo that’s confusing you?

Sometimes one letter can make a big difference and move a location across the country. I was typing an address and I intended to type “CA” for California. Instead I typed “VA” and implied Virginia. I corrected the error, but in this case it would have been easy to create confusion.

I could easily see what I meant. Are all “quick errors” this obvious, especially when the error was made 100 years ago?
