if memory serves.....
Well.......the cruise is basically all 3(4) lanes going south and north along Woodward Ave. It's southern point is Royal Oak MI and it goes North until you feel like turning around. Sort of a giant slowly-moving parking lot.
I was there last year on a Friday night and it was wild. All lanes are packed full of 75% muscle/sports cars. You still get some everyday cars from the people who actually live there and need to get from point A to B but for the most part the road belongs to the cruise.
At 10pm the cops shut it down and block off the roads. You have to go elsewhere.
All the parking lots along the road are rented by various groups/clubs. Last year the Vipers had their own club...vettes...etc. I hung out at the F-body area with Jason D (webmaster) and met some cool people.
GM has a tent along Woodward and last year I was told GNX #1 was there. I never got to see it as it took several hours of 'coasting' just to do Woodward going south. GM was on the northbound side :-(
This year I will be starting much earlier so I can do both sides.
I saw a lot of TR's but as there are 3(4) lanes going each direction.....it is hard to actually get next to each other unless you start out together in a big TR mass
The sidewalks are packed with spectators cheering the cars. Many a time did I hear "wow...a GN....and wow...T-tops"
It is a blast.
