With temperatures staying cold, the hill has become a perfect place to sled. More than 50 hearty Putnam County residents were making the long climb up to the top of the hill to enjoy the roller coaster like thrills of sliding down in saucers, toboggans and sleds. The village of Mark has a skating area as well as sledding hill in the park for Putnam County residents to enjoy. Other hills around Putnam and Bureau counties have also been busy with sledders, as they enjoy the winter season.
