I decided to shut down MHS because I no longer have the time to upgrade and promote it. There are similar services (Google, Esri, Fulcrum, GISCloud, ...) offering better functionalities for free. The GIS field evolves rapidly and we see many new players creating better and better products.
I hope you enjoyed MHS and I wish you happy hiking. Shall you need a backup copy of your data, do not hesitate to contact myhikingspots @gmail.com.
