SWB & I love PA...Having peacefully seen one anothers point I'll tell about my personal example of WHY THERE ??.
I used to spend the summers on my grandparents farm in western Ohio. Come the end of the school year and I'd be on the bus to the farm to help out untill school started again. They passed on long ago.... the farm is still there but the cows in the pasture are new ones. Why did they have to update the cows ?? I don't know. From that altitude one cow pretty much looks like the other. New cows and yet the deck I built on the back of the house 4 years ago dosen't show up here in central NJ. go figure.
