[quote="Dave Noisy"]Heya, enjoy the logging!
You need four bottles of water to ride 18 miles..?
Yup! Thirsty work, especially in warm summer weather. It's on a trail that's mostly uphill, levels out a bit, has some downhill and uphill. The reverse is all uphill with some plateaus, then lots of downhill towards the end. It's fabulous exercise though! And a gorgeous view, beautiful biking area.
