While riding six mile yesterday, I noticed a bunch of places where people were skidding (locking your rear wheel) in to turns and other places. I know there are a lot of newer riders that ride there and that are on the site in general. Please take note that in no case is skidding considered cool or necessary. Sure, everyone skids from time to time, especially when you are trying to ride faster but it should not be a common part of your riding. I rode with some people on here at Mercer and noticed a few of those guys skidding just along the trail. Skidding causes erosion and could possibly cause ruts if the trail is soft. Keep it to a minimum!
