We were in DTW on Christmas morning, landed on 22R. Taxied North on Alpha, then Victor to hold short of 22L, then joined Kilo Northbound toward our gates. The runway was beautiful, but the taxiways were pretty treacherous. I had to keep at a crawl the whole time with while riding the brakes, especially due to higher idle with engine A/I being on and the airplane being VERY light. I was not happy. Wayne County usually does a better job than that!
