Serpentine Drive, schenley park

Out of curiosity, did you use the clue at all, or just know where it was? I like my clue, but wasn’t sure it could be useful.

I was 85% sure I knew it, so i did google search on the chemical make up and confirmed the location.

NEW TAG!

I will try and come up with a clue, but this is a fresh paint job probably passed by between 31 and 40 bikers a day

Additional hint.  This is a fresh paint job and you won’t find it on google map.

Secondly, Jack White played near here.

Is “31 to 40” a hint, or an unusually specific traffic guess?

It is a hint.

Let me know if more is needed, it is always hard to tell if it hard to find or not being seeked.

So apparently my new paint job wasnt complete and now my tag is gone.  Here is the building from my car.  Sorry no bike.
