The State spent a bunch of money to keep us from falling off the old trestles - even though to my knowledge no one has ever fallen from one. There are now cyclone fence guard rails along all the trestles. As a part time rock climber the fencing near the Exit 38 climbing area now blocks access to a couple routes.
And in other news I'm really enjoying the cooler weather for my runs. A side benefit is I'm not getting chased by so many yellowjackets and horseflies. Bonus!
