Vintage car enthusiasts and rockabilly revivalists will descend upon the State Fairgrounds this weekend for the ninth annual Back to the '50s car show. The sponsoring Minnesota Street Rod Association, which is 13,000-plus members strong, promises more than 11,000 street rods, customs, classics and restored cars on display, making it the second largest car show of its kind in the world. While the 1950s is the dominant decade represented, you might see a Model T or two. There's also live music, a swap meet, kids' activities and more than 350 vendors and auto exhibits.
