it's a puzzle inside of a puzzle, that's a big hint.

It's part of a classic phrase from the old western movies.

Okay, it's been nearly four years. Can any of our new members figure this one out? I haven't the foggiest.

Or, if the author is still with us, perhaps she could clue us in?

[Mama]

This town isn't big enough for the both of us.

[Slava]

This town isn't big enough for the both of us.

Nice, Mama. Thanks.

Now, how do we work it out? I see only one "I." We need three, no?

[Mama]

Read the capital letters for the first part.
Read the lower case letters for the last part.
The rest is logic. The both of us doesn't fit inside this town.
The clue was a common phrase in an old western.
Therefore, This town isn't big enough for the both of us.

Cool beans. Thanks again, Mama.

You're welcome. That was fun.

That certainly was fun, thanks, I would never have
figured it out, but I am not very good at puzzles,
seem to take more patience than I can muster.
