A. In the early seasons, I usually had to hunt down the locations after viewing the episodes,
using clues from the various scenes. By the now, though,
I've developed a small group of fans, spies & tipsters who kept an
eye out for Dexter filming in their neighborhoods, and would let me know
in advance when something was about to film there.
Between those reports, my own personal reconnaissance around town, and a
few new resources I discovered, by the time the first episode airs, I
already know most (but not all) of the filming locations, and only
need to watch the episodes and match up the scenes with the correct
locations.
This group of helpful fans includes Rick, Ellen, Elaine, Mia, Joel, Susan, Eric, Jeff, Kerry & others. My thanks to all of
them.
I had a few different sources for this one, including Rick, and some photos online that were shot at the station during the filming, and posted on DexterDaily.com. (Thanks, Rick!)
