Strengths:
I like that you use background color to distinguish between items in the "My Favorites List". It makes it easy to read.
Weaknesses:
When the site opens there is a marker on the map without an info window to give details about the location. Would be nice to have the info window.
It would be nice if the map would zoom out to show all points plotted. Sometimes I will make a selection based on distance to travel which is hard to gague without seeing all the points at the same time.
