I just did a three day ride over near Entiat- some fantastic mountain trails.
Of course we did mostly expert only ones (does that mean I was an expert for a couple of days?). Nice tight, steep interesting stuff!
Some of the switchbacks were VERY tight and interesting. One quite exposed face we went down had loads of those- I rode about half of the hard ones. The rest: the exposure and consequences of a mistake had me walking around. I could have made most of those, but didn't want to take the risk. It was a LONG way down and very steep. The real experts would just do a Nose wheelie and swing the back end around. I didn't.
Weather was not so hot (snow, rain, sleet) and along some of the ridges it was darn cold with the wind. The trusty 300 worked excellent- running nice and clean with that fancy carb and essentially no spooge over the 130 miles (most running at about 8 mph avarage).
Here are a couple Of videos for those interested.
