Great news!!! Have a blast in Silver Lake - I'll be thinking of you guys wishing I could have went!!
I was at the Ganny this past weekend (on my dirtbike unfortunately) scouting out some good trails we can hit on our trikes... it's got so many different types of riding terrain you guys will love it. From dirt hills to sand hills to creek beds and off-camber forest trails, you'll NEVER get bored riding the Ganny!
Here's some footage I took while there to give you guys who have never been an idea of what it's like:
