I took a day off and hiked up Twin Peaks (actually, only the higher, east peak) from the Three Points trail head. I saw no one the entire time. Temperatures were in the mid to high 70s and it was generally clear. I made it to the summit in 2:19, ate lunch on top, and completed the round trip in 4:56.

Three Points to Twin Peaks
Hooky Hike! Pictures are cool. They never quiet capture what you really see there though. I know those flowers were way more vivid than your pics.
