Weather, Good chance it may rain. Pennsylvania's largest industry is still Agriculture, but interestingly enough, you see little irrigation. You don't have to get too far west in an airplane and the crop circles become apparent. Enjoy your trip, better than 1/2 the population of Pennsylvania is in the Southeast corner, Bucks, Burk, and Philadelphia. Again, Good chance, it's going to rain.
