I have many fond memories of Cain Park. The outdoor theater is great, the trails are great, the wooded areas, picnic areas and open fields are great.
But my favorite memories are the huge sledding hill at the east end of the park. A long, wide, smooth slope with a great little hump across about half of the bottom of the hill. A hump of just the right size and shape to make rocketing sledders either catch some decent air or separate from their sleds in comical spills.
The hill faces west-northwest and stays snow packed and icy a good deal of the time. On any given winter weekend you can watch scores of people cavorting, bouncing and crashing about all over the sledding hill at Cain Park.
