Last night I found acorn shells in the car, above the glove box. I opened
the hood and found a lot more shells in the engine compartment.

There are lots of squirrels in the neighborhood so I'm pretty sure they are
getting in the car at night-the car is not in the driveway during the day.

Other than a shotgun, is there a good way to keep the squirrels from
invading the car??

Thanks
