Besides the fact that it sucks? J/K. It's really a personal preference. But, seriously, I'd rather do Peters Canyon a hundred times before wasting a day at Fullerton.dhoffroad said:
What surprises me most is how the Fullerton loop is the closest trail to Anaheim. That doesn't sound right.
For starters, Anaheim is within a hop, skip, and a jump from the 55 freeway. The 55 will plug you into such majestic trails as Irvine Regional Park and Santiago Oaks.
I think you and your rig would be much happier frolicking in those territories.
