Additionally, an exhibit hall containing state-of-the-art manufacturing processes, quality, and supportability displays showing computer systems, software, equipment, machines, and other related items will be open during October 4th & 5th.

OTHER GENERAL POINTS OF INTEREST

The second week of October is a great time to visit New England. It is the foliage season. Within an hours drive you can savor the fabled New England foliage among covered bridges and the cascading waterfalls of Kent in the Berkshire Hills of Northwestern Connecticut and Massachusetts. You can visit Mystic Seaport/Marinelife Aquarium on the Connecticut shore, Foxwood Casino in Ledyard, Mohegan Sun Casino in Montville, or Sturbridge Village at the Massachusetts/Connecticut border. New York City, which is great for exciting activities like Broadway shows, opera, shopping, museums, dining, and sightseeing, is approximately 90 minutes by car or train.
