Recently, I flew to and from NJ during the TFR in Rehoboth Delaware, and had my route amended. Nothing difficult or crazy out of the way, but I didn't see a "how to" on this in my current Garmin 480 playlist. I added a video to the playlist addressing the amended route, potential hold, and finally a direct to destination. I want to mention the great service from our surrounding ATC folks. Shout out to Patuxent, Dover, and Atlantic City Approach Controllers.
