This week, "Summer Guide": The annual roundup of summer tips 'n' activities seems to be telling us: Calm down. Do it yourself. Get in touch with the Earth. Except for those darn Segway polo games, that is. Otherwise, you're advised to pick your own fruit in Brentwood, raise your own chickens in the backyard (marvel at the fresh eggs), ride your mountain bike, take in a stage show at Walnut Creek's Playhouse West, read some of the many books about siblings, or, when all else fails, get your psy-trance on with DJ Bassnectar, bomber of the stars.
