Wunderlich County Park is a nice place for an arbitrary hike, and this one is pretty arbitrary.
The general plan is to string the trails together to cover about 8 miles through mostly wooded, moderately hilly terrain.
The overall pace will be fairly brisk, but with stops along the way for views, newts, fungi, or anything else of interest.
Bring: lunch, water, and such layers as seem necessary for the day. A change of footwear might also be a good idea.
Meet at carpool point #6.
So what if it's a bit drizzly? The trails shouldn't be too muddy yet, and a hike in the drizzle can be fun!
Directions to LPSS carpool point #6 (Page Mill / 280 Park 'N Ride): Exit 280 onto Page Mill Road west (Los Altos Hills) in Palo Alto. The lot is next to the freeway. If looking for overflow parking, beware of the "No Parking" signs along Arastradero. Map: http://tinyurl.com/2tq9rk
