San Bruno Mountain Summit Loop

This is a short hike which is very close to SF.  I found it on bahiker.com within a list of the best wildflower hikes.  I knew that the wildflowers in the Bay Area have been blowing up lately, so I figured we would give this one a try.  We were really impressed with this hike.  Huge variety of flowers, lots of them, short distance from SF, and not that well trafficked on a weekend.  One thing to note is that the flowers were mostly in the first half of the loop if going clockwise.  You could do a condensed version of this hike, and still see some really good stuff.

Eileen found this weird fruit growing on the trail. 
It has the size and shape of a lemon, the skin color of a watermelon, and spikes.
