Hi:
Just to let you know, there are other 55+ communities in the Vineland Millville area. Unfortunately, some of these are smaller with limited adverting budgets but offer a more personal touch with the charm of a small community within a community.
I am aware of a pretty nice units in Millville that closer to Vineland but with ready access, mile +/- to the new shopping mall & stores in Millville & Vineland.
One particular community is Holly Hills Active Adult Community in Millville. It is a 55+, age restricted community in Southern New Jersey.
I believe the website is
www.HomeinSouthJersey.com
The Lightning Racetrack is being built out by the existing airport south of the City of Millville. There is a lot of housing developments going on in that area
I would be concerned only because I have been to Englishtown and it is definitly loud. I would like to believe that it has been taken into account but I anticipate the racetrack is going to be signifcantly larger with wood etc to buffer the noise. An airport has been there for years and I have not heard much about the noise.
Also, try the Millville Chamber of Commerce, they also have a nice website.
Good Luck.
