Cool...I find them too, and think it is from some of the places I park. Once traveled 30 miles with a odd looking spider on my door.They sure got some good sticky stuff on their feet to withstand the speeds. Now that is good free travel plans. You sure would have a hard time spotting this on a tree or bush.
