Being Tracked

Although I live somewhere in the vicinity of Toledo, Ohio, I am currently on a business trip to Denver, Colorado.  My internet access is through the wireless service of the hotel I am staying at.  When I posted the previous entry, the google ad that appeared almost immediately was for a Denver deal of the day.  So how did whoever know I was in Denver, or is that just coincidence.

I suggest that the IP address I am connected through indicated Denver and that was used by Google ads to place the Denver ad in my post.  Will that change when I go back home.
