Kirk you gave me the opening I've been looking for. The answer is IP is a Canadian class. They are close to IT but some differences, incidentally it's no longer CASC but CACC? and recently I checked the web site and there is discussion/rules proposal to align the IP rules with IT.
Kirk knowing of your interest in Westwood, yesterday I hired on at Allard Contracting about 20 years to late. It's the gravel operation at the base of the hill to Westwood. I was looking at air photos of the development and turn three still exists, it's in the greenbelt between the gravel operations and the housing. When you look at the photo of the development there houses built as if they surround the hairpin, and a group that are built in the paddock, it was a strange picture to see.
Finally after Bill's grief with Volkswagen weights the Conference rules are on-line at http://www.ICSCC.com in pdf format, check the production rules. Sorry for bing long winded and slightly off topic
