luegrass Region members are invited to our second B annual Indoor Winter Concours Saturday, February 26th, from 5:30 to 9:00 pm. The theme is Porsche's latest hallmark, "Porsche Intelligent Performance". In tune with this we're looking for more competi- tion and performance cars. We'll also decorate the front windows with as many 356's as we can collect. With fifteen or more 356's from the Drei Staaten Gruppe, a timeline of fifteen or more historic competition cars, a collection of fifteen or more Driver Education, Club Race, Cayman Inters- eries, Grand Am, and ALMS cars, fifteen to twenty late model high performance Turbo's and GT Cars, and a display of current new car offerings, we'll have plenty of Porsche performance on display The event is no charge, but we are registering our guests. We'll be serving champagne and light hors d'oeuvres with Chef Dan Knecht providing a live cooking demonstration. Please RSVP with me or Amanda at Chris Rieman's production at: http://www.youtube.com/watch? [email protected], or (859) 468-7566. v=pEirgCyKB8o . After the Concours we hope you'll join us at the National Ex- emplar for the after-party party. This will be a cash bar. As always, we're grateful for your participation.

We did not get out to the Silver Auction house, so I cannot judge their operation. One thing for certain, if you are thinking of purchasing a classic or exotic at an auction, do your research beforehand, set your limit and let opportuni- ties pass you by if necessary. The professional bidders are well rehearsed at this, although even they get into emotional bidding at times. Amy Lassiter on the Barrett-Jackson stage can be subtly convincing with rival bidders. Many car owners stay close to their vehicles, polishing and arranging literature and are very happy to show you their car and talk about its history before it rolls up on the block. Great opportunities do exist at the effort to attend and enjoy these soirees, so it is well worth the week!
