Ummmm......kinda sir, starting us out with a track that was in existence for ONE race weekend is a bit naughty of you, dontcha think?
I did think about it for a bit...I figured it was unlikely that someone would immediately recognize the circuit. However, I felt there was enough clues in the pic for a clever sleuth to get to the bottom fairly quickly. To wit:
You can google all the sponsor names and guess that it's in the US;
You can guess the weather by the dress of the crowd, which gives you rough region/season ranges;
You can guess temporary / street circuit by the safety measures;
You can guess that it's a mid-major race series by the crowd size (IE, obviously not an F1/Nascar type venue);
You can establish that it's within 10 years by the look of the Porsches;
And with muskrat eyes, you can read the "Long Fence" sign and determine it's in the DC region And also, you can put on your KU clue-deciphering cap and read this...
Eliminating all the states one by one..
...to mean I was indeed planning to eliminate all the
STATES one-by-one, leaving us with DC, Puerto Rico, and Guam as the only "in the US" but not "in a state" locations possible.
In other words, future puzzles will be no less trying.
