Yesterday, I combined two of my favorite Verdugo routes. One was what Hikin_Jim calls the Fire Warden's Grove Loop. It uses two trailheads along La Tuna Canyon Road. I hit it from the top in a clockwise direction, starting at its high point at the Experimental Forest, Plantation, Fire Warden's Grove, or whatever else people call it.
To get to the start of that loop, I sandwiched it in another loop I like to do. I headed up the Mesa Lila Fire Road and the Viper Trail, an informal trail that has combined with a recent firebreak to provide a nice steep ascent to the main ridge fire road. At the end of the festivities, I came down the Whiting Woods Fire Road.
Here is a map. I also posted pictures.

It was a nice overcast day with occasional rain. Air quality was very good. Temperatures ranged up and down from the mid 60s to the high 70s, The only real singn of fire I was was areas that had burned locally in recent years.
The total distance shown was about 15 miles (I also threw in walks to the trail head and back to add another 1.5 miles,) The Fire Warden's Grove Loop was 6.9 miles (people have asked about that distance).
