[Overdrive]

I store my car outside as well, and I highly recommend cleaning and covering the car whenever possible, because the area under the front trunk lid is more accessible than one would think. The gap where the lid meets the lower windshield edge is huge, which is great for getting water to drain off the hood, but I once found a piece of a pizza crust that some critter must have dragged in there with it one day, sitting right on the plastic cover to the right (car's right) of the battery. I can't tell you how long it had been there...I may have even driven around with it there.

Clean her up, keep her covered whenever you can, and you'll get a lot less junk near the drain holes.
