Hi I am looking at setting up my own geocache route, and I have read all the instructions and how to have them checked ect. I am doing as a challenge to some young people I will be working with over the summer, however I will maintain them afterwards. I was just wondering who decides if they go live on the free app is it purely if the difficultly and terrain is below 1.5? Thanks in advance for any help Gemma
