Hi Aaron,
Great site and some very good tools, don't know if its a bug or not. When i did a search on your, Coolest Keyword Research Tool, with the keywords:
"colorado united states" the results are for "colorado united state" without the "s", so then you click google trends no results are returned. I know there is google trends for "colorado united states" because i have checked. Thought you might like to know.
Regards
Gary
