It's common practice to indicate "I" Street in DC as "Eye" Street.
> It helps keeps the postal clerks from squinting.
Sorry, I cannot help myself. I do not plan to make a habit of replying to digest postings 25 years after the fact. But I had to chime in on this one.
The original poster had indicated an address on "Eye Street" in Washington, DC. Someone corrected this as being "I Street" which earned the response above.
I pulled up Google Maps and confirmed that it'll accept either "I Street" or "Eye Street" for the same street in The District. Of course pulling up Google Maps in 1982 was not an option. When this was posted, both Sergey and Larry, founders of Google, were a mere 8 years old.
