Moved to within sight of ESPN in 1992. First morning I was, living in my Apt, I had the window open a crack and hear a whooshing sound. Open the drapes and see balloons lifting off not far away. Got in the car and found the lot where they were. Got to see at least 2 dozen lift off my first morning in CT.
When I lived in CA, would have to take 1-80 up towards Sacramento when I had a job up that way, Would often see balloons lifting off the farmland to the south or see them just over the interstate in the morning.
