pulling over in the rain

i have a cold air intake in my 200

today on the way home from school it started pouring...i've avoided rain until now so it was my first time dealing with the inevitable situation

so it was raining real hard and puddles all over the place so i pulled over into a parking lot and waited for about 45 minutes till the rain slowed down

my question is....was i being too cautious?...should i have just driven home and not worried about water being sucked into my engine?

thanks
