Agreed.
I'll ride in rain if I get caught in it. If rain is threatening before I start a ride, I'll take a rain jacket. Usually, if I pack the jacket, it will absolutely not rain.
If it's fairly warm out and I get caught, I don't worry about it. The rain cools my core.
Don't forget to be careful not to ride on roadway marking stripes if it's wet - very slick.
