Anyone else give it a try?
Any comments?
Seems to work fine for me. Might try it on some mountains, so you can use the 3d aspect.
Park and Rec here in Idaho started some of this. http://parksandrecreation.idaho.gov/recreation/snowmobiling.aspx
You might pop them an email, and ask if their already doing this. They might be interested in the results, your working on.
I have ran across another website, that was putting google earth trail maps together. They had a huge collection of google maps, but they charged for access to them.
It would be great to pin mark some good riding areas. Lots of people go into a new area, and have no idea where the riding is. McCall would be a good place to start. Mark some of the more famous routes. Nothing too secret.
