Good point. When I first "planned" my trip, I figured I would ride 50 miles per day - 200 miles total. It made sense to me. What I failed to realize was that, while my destination of a dam 100 miles away was a fine destination, there was nothing but fields until I got there. And I do mean nothing but fields until I got there. A few seconds of talking to somebody would have helped me realize that.
And - here's the kicker - the campsite with the hot spring WAS MARKED ON MY MAP! I didn't even look at it.
