The place I like to wreck dive the most would be off the coast of New Jersey. There are THOUSANDS of known wrecks of vairing depth and condition. Many are actual wrecks and others were put there as artificial reefs. There are lots of military ships but also oceanliners, tug boats and even a sunken anti missle tower. The water is a little cold, but the visibility is actually pretty good....usually.
There are some really nice dive shops and many great boats/captains for hire. There are lots of artifacts for the junkers (like myself). If you like lobster, you are in luck...they are all over most of the wrecks and are usually HUGE....big bonus it is legal to take them!
If anyone is interested I can provide a bunch of info to get you started.
