In the fall during peak color season I love to run Argentine Pass and McClellen Mountain. Peak color usually occurs near the end of Sept near Georgetown.
These trails are not too difficult and can be done without too much difficulty with stock off road vehicles. There is some exposure due to shelf roads and one large step that seems really worse that it is.
Throwing this out there early because we have a lot of new members, and they are great trails.
Date will have to wait until we know how the fall progresses. Feel free to comment and discuss thoughts and ideas.
