This national park is a great place to visit and to learn about a great American and all of his wonderful inventions. Our family has been there numerous times, and each time we go we learn something new. Edison's was the first real industrial research and development laboratory, and it is fascinating to walk through the buildings and see how dedicated he was to creating new things. Down the road you can visit his house and see how the wealthy lived in the late 1880s and early 1900s. The only disappointment is that I wish more rooms in the house were open to the public. We are so impressed with the park that we've even written a blog entry about it: http://www.squidoo.com/thomas-edison-laboratory-new-jersey-day-trip
We highly recommend the park for everyone!
