I'm planning to pack lightweight (duh) rain gear - pants and jacket. But I have some questions/uncertainties.
1) Do I need them through SoCal?
2) Why do people also bring an umbrella? I only find umbrellas useful when walking short distances in rain that's falling straight down. If it's windy, an umbrella is useless. If there's lightning, it's dangerous. Not something I was even considering until I saw others talking about it.
3) What about a poncho?
