Just back from PI - hadn't been since '09 but can thoroughly recommend it for bucket lists.
The circuit alone is worth making the effort to get to, and then the variety of cars - many of which we never saw - is a real treat. The logical thing would be to combine that meeting with the GP.
Perhaps a TRS team trip next year - there are camping grounds at one end of the accommodation scale, and luxury at the other end.
Met a number of expat Kiwis plus a couple of hard case Aussie based TRS members in John 'Meddles' and the ace snapper Dale from Newcastle - top blokes.
