Hi all, 
Looking to go to leavenworth area for a few days of mountain biking.  Id like some input on where to ride.  If you've been there let me know what trails were good.  Im looking for trails that would compare to surveyors ridge, mckenzie river, mt st. helens etc.
Also Id like to camp, but would prefer to not be in a KOA or anything where lots of RV's would be spewing their generator smoke and sounds.  On the interwebs places like Icicle canyon, specifically bridge creek seem to be right, but I've never been there.
Any thoughts or suggestions would be much appreciated.
thanks for the help.
Dan
