One interesting fact I would like to share is that I grew up in Cochranville, PA (Southeast corner) – A small town with less than 400 people that had many different agricultural system (dairy, beef cattle, ornamentals, vegetables, fruit, lots of different row crops). Spent many of my summer days playing baseball (all day) and many winter evening playing ice hockey – Some fond memories of days before cell phones and computers that still bring a smile to my face!
