Re the mileage comment - who cares. If you can't drive it, what's the point of owning it? Keeping it shiny and parked? I like mine shiny too, but wouldn't own it if I couldn't drive to events like these.
Just to clarify, Friday May 16 is Day 1 at Knox Mtn, with registration and the like (check out the website). Saturday May 17th is the Blossom Run in Summerland (not Sunday). Sunday is Peachland (not to be missed). Knox Mountain Qualifying and Racing is Saturday and Sunday during the day. There is no 2008 schedule yet, but there will very likely be 1/4-mile oval racing at the Penticton Speedway on 1, 2 or 3 of the nights that weekend. This can be and very often is, very entertaining stuff.
Driving to Kelowna up the Coquihalla is quick, direct, but very boring (and laced with Radar, especially as one nears Kelowna). The Duffy Lake Road (Vancouver, Whistler, Mt Currie, Lillooet) and subsequent routes to Ashcroft, Kamloops, Vernon & Kelowna are WAY WAY WAY more entertaining and involve doing what you car was meant to do. At the very least, Vancouver to Kelowna via Princeton, Penticton and up to Kelowna please, no Coquihalla.
I'm already booked at the Manteo. It is outdoor parking, but I've had no issues there so far. There is also a coin-op car-wash just down the road for cleanup prior to making it shiny.
