One thing to think about when doing the Pacific coast in September - rain. I grew up in the northwest. It doesn't rain as much as people say, but there can be long periods of rain at any time during the year - like two weeks straight of rain. This is rare in July and August, and common in November and December. It's worse along the coast. I've done the coast twice in July and August. Once I got two days of rain in four weeks. The other time I got none. My nephew left Victoria in September. He got rained on a lot - probably more than hald the time. He had a cold, wet trip to San Francisco.
I'm just sayin'.......
