Rough Go to Lake Ilsanjo

It's been a while since we've hiked Rough Go trail. We'll hike up to Lake Ilsanjo, stop for a snack at the gazebo or lakeside then continue around the lake and down Spring Creek Trail back to Spring Lake. Most appropriate for those with at least a moderate level of fitness.

Notice to New Hikers Only
After six years and 300+ guided hikes I'm adding a new rule for New Hikers Only Effective Immediately. In my experience New Hikers have a 90% chance of not showing up (No Show) to a hike they have rsvp'd to attend. The new rule is "When a New Hiker (never hiked with me before) doesn't show up (No Show) to their first hike with the group, they will be removed (not banned) from the group immediately." When a New Hiker does attend then the current No Show policy applies after that point.
