Went to good ole Sues Rendevous yesterday for a minute. After doing a 360 with my traction off in a open area (parking lot) I hopped on the Bronx River Pkwy about 4am. I was driving and my car started vibrating...sort of like my friends car when he bent his rim. I didn't hit anything. I drove into queens this afternoon and everything was normal. Do u think it was just snow and ice frozen on the tires? I ll have to make sure again tonight.
