# Not quite binary

Your friend, the Kentucky telemarketer from this question, wants to meet you for a cool field trip! She could have just told you where to go... but that would be too easy, right? Instead, she left you a little note:

1001000 1011010 1010001 1011001 1010111 1001110 1010001 1001011 1011101 1001111 1011011 Be there at 7!

Hint: I'm ???? da ba dee da ba daa

Hint 1:

The ???? is not referring to blue... It's referring to another color! :):)
Look into the connection of Kentucky with the above hint and maybe you'll find something interesting!

Hint 2:

The color you are looking for from hint 1 is not black... it's not white, either.

• I have a hint queued up for tomorrow if nobody's gotten it by then... :):) Aug 17, 2020 at 20:43

I've now definitely got at least part of the answer (or perhaps the whole answer if I was over-thinking it?)

The decoded message is

planetarium
Be there at 7!

To get there... a simple decoding as ASCII reveals

nothing meaningful. "HZQYWNQK]O["

However, there's another kind of

binary code referred to as a "gray code", where only 1 bit changes between each consecutive number.
Rather than 0000->0001->0010->0011->0100->0101->0110->0111->1000 -> etc.
In each case the only bit that changes when counting in the Gray code is the same as the highest bit that changes in a normal binary number.

Using this,

(or "cheating") we can convert to a standard binary code
1110000 1101100 1100001 1101110 1100101 1110100 1100001 1110010 1101001 1110101 1101101
which can then be interpreted as ASCII, yielding the word "planetarium"

It is not clear to me at this time

Which specific planetarium is intended, as there seem to be several in Kentucky https://www.go-astronomy.com/planetariums-state.php?State=KY and none of these are near to

a location I'd identified from earlier clues

combining Eiffel 65 (the band who wrote the words to the hint song) with Kentucky, to get Paris, KY, which has an eiffel tower (quite a small one indeed).

but another more obvious location is available,

Gray, KY

which is

a "field trip" can (normally) be arranged

https://planetarium.eku.edu/field-trip-group-visit-information but I see nothing to suggest it's re-opened yet following the "temporary closure"?

• Not bluegrass, exactly. The hints are a little more obscure than that! :):) Aug 17, 2020 at 23:01
• Maybe see if hint 1 helps at all? Aug 18, 2020 at 12:24
• The Kentucky hint was because there's a town called Gray in Kentucky... :):) Nice job! Aug 19, 2020 at 18:15
