A simple FireFox OS application that determines, using relevant weather data, if you should go hiking in a specified area at a specified time or not.
You will need a Weather Underground API Key. After acquiring your key, create a js/config.js file and create the config object.
var config = {
"wu_api_key": "<your api key>"
};
This app is based on the FireFox OS Boilerplate App by Rob Nyman (https://github.com/robnyman/Firefox-OS-Boilerplate-App)
