I remember those trails.The only time they were good was when they were fresh groomed.They were found to be much more unsafe and the best thing they did was get rid of them.The corners would get blown out and then you were on the wrong side and it wasn't always easy to get back into your own lane.They caused a lot of head on crashes.If you caught up to a slow group you were stuck behind them for a long time and would have to make many jumps back and forth over the berm to get by everyone unless there was a very long straightaway and you could clearly see ahead and safely pass the entire group and then the rest of your passing group also faced the same dilemma.And as VTblue stated they didn't hold up after being groomed anywhere near as long as the trails we enjoy now.Every single sled rode in the exact same track as the sled before it.Imagine if everyone only rode the extreme right now.The trails hold up as well as they do now because everyone can pick a different line and spread the abuse out.Ride right in the corners but where you can see ahead enjoy the smooth parts of the trail.If you want to always ride extreme right ,than thanks for leaving me the middle on the straights.
