Trek Fuel EX. Mostly cloudy with the occasional spot of sunshine, 10-11 mph SSW wind, temps in the mid 60's - very comfortable. First time riding here in Cook County's first Forest Preserve. Mix of mostly gravel, dirt(mud), woodland trails and some paved trails. Nice place, very flowy and non-technical on the official trails, probably better suited for a trail or gravel bike but I had a nice ride. Did two opposite direction loops. Note to self - stick to the authorized trails or at a minimum don't go on trails that say no bikes. I took one side trail that was terrible - boggy and several creek crossings with no bridge. Yellow trail is super flowy and easy, green trail is woodland and nice, brown trail is mostly single track.
