After my usual Bog Trail meander in San Bruno Mountain Park (first pic), started up the Eucalyptus Loop Trail (second pic - near the trailhead), curving round to the east until it connected with the Summit Loop Trail.
Just before the Summit towers, where the Summit Loop connects with the Ridge Trail (third pic), continued on the Ridge for a short distance (fourth photo), then back to the Summit Loop to descend. The Summit Loop connects with the Diary Ravine and Eucalyptus Loop Trails partway down. So today did at least some of all the trails except the Saddle and Old Ranch Road.
Continuing down the Summit Loop (fifth pic) there was this bicyclist heading up. Second time I've seen a bicyclist up here (despite the no-bikes-on-trails icons on the trail markers). How they can navigate a bike on these narrow, rocky trails is beyond me.
Twice on the Summit Loop and twice again further down on the Eucalyptus Loop, a small furry mammal darted across the trail a few yards ahead. The first two on the Summit Loop were kind of a light gray, The little critter on on the Eucalyptus Loop a darker gray, and the fourth a sort of brownish hue. They weren't cats. I'm thinking wild rabbits/hares, especially the split-second glance at the second one. They were all too quick and too far ahead to be sure.
'Twas a superclear day with one of the sharper views of the whole world I've seen in a while. Beautiful spring buds 'n blooms along the Bog Trail were reminiscent of my Glen Canyon hike the other day. Neither time on the Bog did I encounter my buddy the Attack Pheasant.
