If you're riding with your husband, you'll be fine.
Sadly, a solo woman cyclist was murdered along the trail two years ago, in a quieter section of the trail. The man was captured almost immediately and the trial,I believe, is going on now. (Or else there was a recent hearing.)
And more recently, a few assaults on a sidetrail leading up to the main trail. In this case too, some of the kids were arrested.
It's so sad, since it's a gorgeous area and a great place to ride. As long as you're with your hubby or a friend and stay aware.
I used to ride out there all the time, hundreds of miles, and never had a problem.
For 3 days, I get to part of a thousand other journeys.
