If it's middle to late October, I might come down for it! I will want to visit my daughter in Petaluma about then!
Early October in the Pacific Northwest is Alpine season in northern Washington, so no way would I go elsewhere then! For those who haven't seen our larch trees that turn gold in the fall (IMHO, rivaling the mallorn trees in Lord of the Rings), come on up! The Alpine larch (at higher elevations) is usually best in early October, while the Western larch (at lower elevations) is best about mid-October.
