There is a DNE (Dallas Nissan Enthusiasts) meet on March 22nd.

This is a pretty large group with about 60 members (and growing fast), it was started by a few fellow Maxima owners, but there are all types of Nissan's involved, including my (and others)350Z's.

There have been 50+ cars at the last few meets.
