New York, New Jersey, and Pennsylvania were a frozen world. Fields were snow covered, the air was frosty, and waters were iced over. Here is a sampling.

Judy Drew Fairchild found a great video showing iceboating on this river – Ice Boating at the NSIBYC (note – North Shrewsbury River and Navesink River are the same body of water).

Iceboating brings back very cold memories!
The iceboaters really suit up, and due to the speed helmets are standard.
