This is absolutley perfect!! I just found out about an iPhone app called Every Trail and got to see some examples on their website. I am so excited to try this out! It will track your trail movements and then plot them out on a Google Map that you can share with others. You can also post pictures along the way of particularly scenic spots. This is just what I have been looking for, you can check out the sad selection of Saskatchewan ATV trail maps they have posted on their website here.
Make sure you have this app with you this coming season and share your trails with us!
