i plan on beginning racing next year, i have the 2010 license, i am comfortable on any intermediate (blue) trail and i have successfully ridding an expert trail without any failing. the nearest downhill area, however, has closed down, and i live in a place that doesnt pay much attention to downhilling. winter is coming, and at spring, there will be no trails so. how can i "practice" downhill biking for the winter and spring?
