Maps # 31 Have Map, Will Travel

I have watched Google Create a Map Tutorial for a few times. They are putting out new functions constantly. I use driving directions all the time, but I have learned a lot of useful new things from the exercise, to drag the direction line to change to the way I want to go, to look at the street view of the destination surrounding before going there, etc. I tried to put a place mark on the map. All the places I wanted have marks already. I put a correction request on a wrong mark that I fund instead.
