PS: If you have a choice as to when to come, delay the trip until September (as close to October as possible). The best weather all year is usually late September, early October: warm, sunny, fog-free on the coast. If you do come in August, bring a jacket. Mill Valley is warm enough, but if you plan to come to San Francisco (and I hope you will–just park somewhere and take cabs to your destination because it’s geographically a small place, 7 miles square but the part you’ll care about is much smaller) you’ll find the wind howling and the fog bank pouring in by 4 PM most days. And anywhere along the ocean it’ll be similar.
Oh, and give the kid a bigger allowance–he deserves a chance to get out and explore. It’ll be a better education than anything they teach him in school (take my word for it).[:o)][:o)]
