And, you can get to Main Divide by taking 5 south, exit at ortega highway, go towards the mountains (left), and keep going several miles. After you get past the one lane area from the construction, you'll still go a few more miles, but eventually see the exit for Wildomar to the right. On the opposite side (the left) is the Main Divide trail. At the first Y right at the entrance, go left. You could also go right, but it shoots straight down the hill.
oh, and you might want to not post with the CAPS LOCK ON. It means you are shouting in "net speak".
