Welcome, Miata Stu!
Please, haggis no. But Jersey Roadfood, YES!
I'm Mosca here, Mosca on Miatanet, member of the New Jersey Miata Mob, and former Governor of the Lehigh Valley Miata Owner's Club in Allentown PA, http://www.lvmoc.net
; LVMOC have a number of members from Jersey. I also race (badly) a '97; I autocross in NEPA SCCA and do HPDE at Pocono once or twice a year, but no track racing.
I think there are at least two other Miata owners who are very active here.
