Northern California - Rainy Davis 400k brevet this Saturday?

The weather forecast indicates a rather rainy 400K brevet for this Saturday.
Any tips regarding some useful rain equipment or tips for a perhaps very long ride in the rain ?

Stay away from all the drunk college kids/alumni that will be in for Picnic Day.

Well, he'll be leaving Davis at 6 am Saturday morning, and should be back in Davis between 6 pm* Saturday evening and 9 am Sunday morning, so hopefully he'll miss the Picnic Day revelers.

(* the cue sheet says the finish control opens at 18:08 on Saturday. 400 kilometers in 12 hours? good grief.)

I was going to go w/ the family, but having been to one of the wettest ones in memory ~4 yrs ago or so, I think I'm gonna pass. I don't think lutz w/ have any issues w/ traffic around town if the weather's gonna be wet. ;)

edit: lutz, the only advice if it's raining is to have a cape/jacket that breathes; it's no fun getting wet from the inside.

Thanks for the suggestions,
the weatherunderground forecast is looking even gloomier today,......
