I sometimes reverse park my car inside the garage on a heavy downpour and just sit in the car with all my windows down as I watch the rain come down. You'll should try it, it is awesome.
I like to open the window and hit my bong if it's a nice, steady drizzle. If its really coming down, I like to roll a few j's and sit on my rocking chairs on the front porch. Country life at its finest
