The ability to create an interactive map of your park or trail network is really valuable for many people. I like how easy it is to use and edit information about my parks and trails and share them with others. It's also nice that I can search by specific points of interest rather than having to search through every feature in the system. It would be helpful if you could have more features available at different levels of detail. For example, the site has a "Places" page where users can pick specific places they want to add but there isn't a way to go back and refine those choices. I think this is one of the better mapping tools out there and it is definitely worth checking out. I'm using it to help plan our organization's community trail program.
